the core which 0.5.5 runs on is a way too difficult environment, and only a small portion of the team knows how to work with it, and the core simly isn't powerfull enough anymore, 0.5 allready pushes it to the limit (which is also a reason why the desync occurs)
also, in the current core it seems to be that fixing one bug, create two new bugs
in short: wait for blue
