So, I was battling a Firehawk, went to get a beverage, came back and ALL my weapons were disabled. I haven't disabled or attacked another player in like, four days, and was wondering... Has this happened to anyone else??

Its FlameHawk, and someone used alot of Tactical Inner Bypasses on you, if they didnt then idk why

have you had enough credits to pay upkeep everyday? or do you log on to see 0 credits all the time?

also, there's a mission that has a chance of damaging your weapons

If it was a Tech bypass, I would have been hacked prior to that...

If you are the same Geron from the legion The Sorceron Brotherhood, the mission that you have been doing that gives you the buff: Stable Overcharge : Attack +25 also damages your weapons modules, eventually to a point where they will uninstall themselves due to damage. You will need to repair/re-install all your weapon mods, and with heavy thetas, that's not going to be fun or cheap.
