Update: I was having problems with getting the mod loader to work and with the save function, and I'd thought I'd follow-up.
When opening the game in MS Edge, the save function was not working at all. Turns out it's a problem with MS Edge. It also wasn't working, at least for me, in Chrome either. But, I didn't have the same problem in Firefox. Save function works fine. Don't use Edge. I've seen other HTML games having problems with Edge too.
On the mod loader, I was having problems with the new Java. The modloader would open then immediately close. Found one programmer that said whenever Devs save jar files opened by newer version of Java it can cause this problem. He offered a simple solution . . . a program called jarfix. The problem, why it happens, a workaround, and an executable file can be found here:
