I'm quite content beta-testing the 1.09n patch.
However, I've seen a few mentions of some people becoming a little frustrated with crashes, broken game mechanics, etc. and who might want to play with 1.09E again for a bit while we wait for 1.1.
Plus, we might have a person or two who accidentally install 1.09n, if their Impulse is set to show beta patches.
Is there a way to do this through Impulse? Which doesn't involve a full reinstall?
Note that you can turn off the 'show beta patches' feature in Impulse, which would then make 1.09E show up in the update window, so you could do a full reinstall and then install 1.09E.
