I've got a regression that I can't reproduce with a new save, and I'd like to confirm that it's because of the new build rather than some sort of bit rot. Specifically, I'd like to go from 3075 to 3069 briefly, to test.
No. Not that I am aware off. As soon a Experimental Phase ends it gets replaced by a Public relase Number. Only way to test would be by comparing your find with Public.
I ended up being able to reproduce the problem after all (weird edge case, apparently,) but it'd be nice to be able to roll back to at least the experimental builds since the last release in Steam. I imagine it'd be helpful to the devs if I could say "This broke specifically after build 3073" rather than "uhh this worked back in A12.3, I'm pretty sure?" FWIW, I tried to roll back to v1.1, but there's some sort of incompatibility that causes a CoQ and a hard freeze when I try to load my save in it. Either way, call it a suggestion. ¯\_(ツ)_/¯
