All stone dissapears
 

Playing as a forrest elf all my stone just vanishes into thin air. I havnt built anything for almost 2 weeks, balistas are not shooting I am not even using a alchy lab, and everytime when I log in i have like 50 stone but it just rapidly depletes down to 0.

This really has to be fixed before sieges are introduced to the game as it would screw me over big time
