VERY weird Ghost Mode problems

This evening, when playing a GM game, a friend(IGN:emaricasARMY) and I(IGN:Wolframite_) noticed some VERY weird bugs/glitches. As such, I am posting ALL the details we could collect in order to both clear our names of any accusations of hack.ing, as well as to inform the proper people, so that in the future these kind of bugs can be minimized or removed.

Included in this post are links to a replay AND a video taken with XFire in game. Both of these should help in giving a visual depiction of the glitch/problem.

OK, first I should note that we had been playing together, physically in the same room, for a good portion of the evening, and I know for a fact that neither of us were running any hac.ks or 3rd party software designed to alter the gameplay experience of Crossfire. Also, every game up until then had played out smoothly, with no problems whatsoever. Then, we decided at around 11:30 PM EST to join into a Complex GM room, located at Alpha 7-9. Immediately, I noticed a problem: a "Disconnected from Server" dialog appeared on both mine and emaricasARMY's screen. However, neither of us were disconnected: it still allowed us to both continue into the game.

Once we got in game, we watched the remnants of the round of which we joined in the middle, and then we began to play. However, emaricasARMY noticed some VERY weird effects. First, he was not listed on the roster of players. He simply was not there. However, he could still move around and play as if he were. Then, something even weirder happened: emarica noticed that he was bulletproof. He simply would not take damage as a ghost. After spotting this, he immediately began recording video in-game, so that he could report these symptoms. Also, when he did score a kill against a soldier, rather than the normal method of reporting "emaricasARMY [gun type] person killed", it merely had the skull and crossbones as in when somebody dies from falling, and the person who was killed by emarica.

After that first round was completed, something even more odd happened: rather than resuming the next round in the normal spawn for ghosts on the map(Complex), emaricasARMY remained where he had been at the end of the previous round. After this, emarica simply played a few rounds that way in an attempt to gather useful and meaningful data for the report. This can be viewed in emaricasARMY's in-game video, link posted below.

However, while emarica was experiencing these symptoms, I was seeing quite a different story entirely. Instead of seeing emaricasARMY(as aforementioned, he was NOT on the roster of players), I saw some other teammate, IGN:moufy, moving around in a very erratic pattern. Also, this player, moufy, appeared in the same spot emaricasARMY was during the match(since I was physically beside emaricasARMY the entire time this happened, I was able to confirm this), and any time emaricasARMY killed someone(even though it appeared as though they killed themselves), that person would see moufy in front of them, knifing them, instead of emaricasARMY. Needless to say, this presented some frustration to all players involved, as this behavior directly hindered enjoyment of the match.

After emaricasARMY felt as though he had gotten enough video feed to aid any developers in addressing the issue, he exited and uploaded the video via his xfire profile. I stayed in-game in order to save the full replay, from which you can witness how players other than emaricasARMY viewed the incident.

A few other details we noticed that may aid in debugging:
-emaricasARMY would see that he had the bomb at the start of every match, although everybody else saw the bomb on another person
-Other people could not see the text emaricasARMY attempted to type in the ALL chat channel
-Occaisionally, a kill made by emaricasARMY would display as being done by moufy(noted at 3:17 in emaricasARMY's in game video)
-We noticed that EdVanHalen was exhibiting gameplay behavior similar to those of a person who was wall hack.ing or chamming. Perhaps this interfered with emaricasARMY's gameplay?

Both I, Wolframite_, and emaricasARMY are attempting to cooperate in a manner that will resolve this issue. However, we both feel it important to reinforce that neither of us were running any hack.s or 3rd party software that would be responsible for this kind of behavior, and it did not seem as though the player with IGN moufy had any control over this behavior either. Sorry that this report necessarily had to be so long, and thanks in advance to all readers hoping to provide support for this issue.
