When I open the powder toy beta, all is right, bur when I click on it to put an element, it disapears from nothing. What do with the powder toy beta? the non beta work correctly. I downloaded at leat 5 times, but nothing works. How to resolve this error?
This seems to be an all too simple error, atleast the way it was described. I'll go look at the changes on Github. Either way, it will be fixed soon.
EDIT: Also, two things I should say. First, does it happen with every element? Make a proper bug report, not this crap. Second, one the kid files a proper bug report, open Powder Toy with GDB, follow the steps to reproduce and pastebin the results. It will allow developers to fix this sooner.
