I'm aware of that right now. I'm currently trying some backup procedures on the server, but the system become overloaded and things are happening slowly. Plus, there is a 10 seconds timeout for the compiling requests, so the builder just stops waiting and nothing more happens.
First i will remove that timeout, because unfortunately even if something is fine, metaeditor.exe (which is also the compiler) always starts very slow, with at least 2 seconds delay, which makes all compilations 2+ seconds slow. Very bad, I tried to find a way to resolve this, but no success.
