ok, so everytime i open the buy menu my game freezes and is no longer playable so i have to end program with Ctrl+shift+esc and play again. but its only when i have mods. so far i think the culprits are DStech, DarkStorm OR Unitec. those are the last three mods i removed before it worked. i.e i had a load of them, i removed them 1 by 1, and those 3 i removed all at once. they were the last ones i had.

Are you sure all three are the latest versions? And not modified in any way?

really hyper? [nvm]
I'm guessing its because of presetname length. One or more of your mods, have a gun/actor/bomb with a name longer then 11 letters.
[11 consecutive letters in the name]
Eg. LousyManofWits will freeze the game, however,
Lousy Man of Wits will not.

Edit: prices also create these. Such as 10000000000 will not work, but 1000000000 will.

Ahh i remember when Gotcha worked that out and told me on Msn, i just didn't think to checkk that, i'll try again and post results
