Assertion failed errors

Just today, i cant even remember what code i added to make this happen but every time my code compiles i get 21 ‘Assertion failed: (x reason)’ errors with many having seemingly random reasons like ‘Command 3’.

It seems to only be an error that affects builds because my game works fine in the editor but in the build version i cant use any in game UI elements. I have looked the error up and seen a few bug reports of it but not sure if this is on my part or just a bug, thanks for the help!

Well … uhm… after like 3 hours of trying to figure this out…

I just had to restart my computer. Done.

The full console log is:

The Issue is still present, now with unity 2018, i have it still here, with about 163 scripts are attacked - with the instance of this re exception issue. Will Unity please, care, to explain this here, and is there a way to shut this warning down, on the console, please, thanks in advance ?
