Greetings! First I wanted to say thank you for this excellent set of mods. Progressive has helped breathe new life into the game for us, and we've really enjoyed the challenges and unique gameplay it has provided.
I'm unsure if you are looking for the community to contribute any issues they find, but we happened upon one with the Warlock today. I cannot be certain if this is specific to your progressive mod changes or House Rules in general, however I think it is potentially related to the enhancement you have in progressive that makes the Warlock immune to corruption.
On my partner's final action of his turn, he was able to repeatedly move to tiles with corruption (about 10 movements in a single turn). Each time he stepped on a new corrupted tile, he would be temporarily corrupted before it was removed and his action was reset. Unsure if it is map specific, but this occurred on one of the castle(?) maps, second level, Serpent Lord campaign.
Additional info: This issue occurred on PCVR. He was hosting, we were each playing two characters. This occurred on the latest v1.7.5 release.
As an aside, is there a known issue for non-hosts regarding the UI appearance of the new cards? They do not have the background card appearance that the regular cards do. I also have an issue where the correct costs are not displayed (e.g. cards show as 1 cost when they actually cost 0). I can create a separate issue for this if you are accepting issues. :)
