No I didn’t set it off, I don’t think it’s a good idea to turn the cache off. However I didn’t empty it as suggested by another user above, and I’m going to do it because it makes sense: if they changed the data format in some places, then the ancient data may be no longer compatible with the new version and thus cause crashes. This may explain why some of the crashes are seemingly random.
If my hypothesis turns out to be true, that’s something Asobo should have written in their release notes. But now I’ll clean my cache after each new patch.
