[Bug] No response for some Actions

Hey guys!
1. Im sorry that i forgot the /debug option, next time i'll occure it'll be done

Now the bug itself, it occured in the game titled "Game of Antz" at Feb 18th, 16:51
2. As the game gets near to the end the fps drops to some value between 2s and 0.5s
3. Then im not able to build, upgrade or change strategy, if i try it seems like the tower is beeing build but it stops, so the space is blocked just on my screen thought!
4. Even if i send (it is possible!) i dont get any more income

My System:
Ubuntu:

  Code:

Linux XXX 3.0.0-14-generic #23-Ubuntu SMP Mon Nov 21 20:28:43 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux


Java:

  Code:

java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode)

CreepTD
is running in Default Skin mode, with minimal Graphics.
As i am aware java on linux is not a very "stable" programm, so i guess its just because of that. But still the Maps are way to overcrowded in the end.

Do you have a high CPU load, when this bug appears?
