The “Reduce Corruption” monolith node isn’t working properly. The “choose how much corruption you want to remove” screen won’t go away, and I think the buttons stay active* - I chose the option for -10, and dropped from ~340 to 194
*In the space of several minutes I left the instance, teleported back to End of Time, ran around for a while, opened various windows, ALT-TABbed out - couldn’t get rid of that panel. Had to stop and restart the game to get rid of it.
