In my old community we had only a single compiler that could decompile STEF2 maps.
And it was a bit buggy, so I wrote the developer a Email and got a reply.
Recently this decompiler was updated to also decompile MOHAA maps correctly, so I thought I share it here.
I can't tell if there are any bugs left, as I don't really map in MOHAA.
