Gah, the forums stopped notifying me about this thread, sorry I missed this. A few notes:
1. This 3.120 version was an official release, so you'd see nothing under the beta section, but just info on the official section in the updates tab. Seems to be working fine, but if you're used to looking for the beta I guess it could be easy to overlook.
2. The manual patch this time was just a zip file containing the patch contents, so you did the right thing by just unzipping that. I should have created a literal manual patch, but I forgot about the need to do. The Tidalis process is so much better, and I can't wait to have that ready for AI War in a few months.
