I found a bug in AGS 3.1.2, but it's no porblem in AGS 3.1.1
I create a translation file, and translate the GUI string.
but when I run the game, the string in the GUI is still havn't been translated.
That is Translation function invalid in the GUI string in AGS.3.1.2....
Thanks for reporting this, it does indeed seem to be a bug in 3.1.2.
A fix is now available in 3.1.2 SP1, please check out the other thread.
