Well for me I got a desynch the second I tried to load in, and for Brilland he gets an error "Cannot join. The following mod script filed are not identical between you and the server: "mod-RealisticFusionPower""
If everything looks stable on your end, can you publish an updated version of the mod so we can just update through normal methods and test?
That's my fault, I should've specified that you have to replace it for everyone, including the server.
Update to 1.7.4 the normal way, the new control.lua is in there.
well now I'm getting a desync too (as soon as loading into the game - didn't even get around to the pipe test). And when I load the game in single player (then put antielectrons in a regular pipe), it doesn't do a proper "punishment" for putting the wrong things in the pipes; it just... draws yellow lines all over?
Everything works fine on my end, so I have no idea what could be wrong there. Try updating to 1.7.4, that should hopefully fix it.
