It seems the displayed remaining time is about half of what the research actually takes despite my research production and consumption being pretty stable. I'm not using any mods affecting research speed. I can send you my savefile if it helps you debugging the issue

I pretty much only made the minimal updates to make this work in 1.0/1.1 ... if somebody sends a minimal patch I would be happy to check and apply it and push an update, but I don't have time to investigate why the time doesn't match for your set of mods.

Are you sure gamespeed is at 60 UPS? This mod cannot know UPS and has to assume it's at 60 so if you have a big base and your UPS is low that is why

Ah right, that is probably the cause. My current PC is too slow to run my map at full 60fps
