I just downloaded a new version of the mod and tested it, I put redstone latch and connected both ends to itself and nothing happened. So I tried with an inverter at one end and then game crashes again (in order to replicate this you need to change the state of latch)

Also another crash with latch. Place a latch connect redstone dust to it and click it again (you need to hold redstone dust with anything other it doesn't work)

game now crashes when anything connected to latch is updated ._.

I actually have problems with replicating the issues this time, could you send me the full game log and screen shot of the problematic setup? Because I'm clicking and placing those latches all around and nothing crashes

OK, after some more testing I found the problem and fixed it. The new file on curseforge has the same name as the old one (red-bits-1.4.0). I will leave this issue open for a couple of days - just in case
