Hydra Money Bug

In my last game i bough the RevHydra but once i wanted to switch to TitanicHydra i lost 3600 gold and since i only had 307g at the time i had negative money out of the sudden. I wasn't able to buy anyother item or redo the "purchase" for the rest of the game. So basicly i was forced to play with the items i bought up untill than (the Revhydra didn't switch to Titanic btw.). There is nothing much left to say about the. Here is what i did to create the bug. I was alive, i clicked on the itemicon in my itemshopinventory to open the buildpath of the item, than i right clicked on the titanic to switch items and finally i lost 3600gold and wasn't unable to buy, sell or redo anything.
