vcmi/server/CGameHandler.h
Michał W. Urbańczyk 13f26fc3cb * Client is able to await for answers for multiple queries at the same time
* Hackish solution allowing AI undertaking actions from event-handling thread
* Fixed crash when death stare or acid breath activated on stack that was just killed
* minor fixes
