So i thought id take part in the beta, but then i found out that CoH2 then had deleted all my projects that i was working on. I have a feeling, if i opt back to the old version, i don't have the map files there anymore. If that is the case, im done with mapping.
Im not sure, but if you have them exported, you should be able to unpack them. You might have lost some of your most recent unexported work, but maybe it saves enough to keep your interest?
