Description of the bug (and if possible, steps to reproduce the bug):

openjk_sp.x86_64: openjk/code/game/../Ratl/handle_pool_vs.h:151: ratl::handle_pool_base<T>::TTValue& ratl::handle_pool_base<T>::operator[](int) [with T = ratl::storage::value_semantics<CTroop, 100>; ratl::handle_pool_base<T>::TTValue = CTroop]: Assertion `is_used(i)' failed. 

Can happen anytime but it appears on level t3_byss crashes often during playing.

Stack trace (when playing on t3_byss):

The game crashes during playing.

The same error always happens if I save the game on vjun1 in the acid rain (it is important) and then I try to load the game. The program crashes before the progress bar appears during loading. The stack trace for the assertion error:

What did you expect to happen instead?
The game should not crash.

[ensiform]

It's an assert that may or may not still need to be there. If you use the release build as opposed to debug compilation it won't "crash"

[etasnadi]

Thanks, then I will remove the assert if you think it is not needed anymore. I thouht that the code is not functioning properly on my system as there is a good reason for that assert to be there.

[ensiform]

I didn't say it was for sure not needed. But you shouldn't be playing with debug on a normal play. If it crashes without the assert or release compile then it is definitely needed

[etasnadi]

I rebuilt in Release and it does not crash anymore (not in the cases mentioned at least).
