I changed the factorio-version in info.json and it loads ok, although it doesn't work correctly in-game. The ghost item doesn't always change to a normal belt when laying down the replicating belt. See the screenshots (edit: I added a second screenshot with only replicating belts as activated mods, same issue) :

I've tried to debug the mod using vscode with the factorio debugger addon but I haven't been able to fix that. I don't have enough experience with factorio modding but I'm wondering if that perhaps the create_entity() call (in the check_path() function) can't create a normal belt because the position is already occupied by a ghost replicating belt.

Broken due to https://forums.factorio.com/viewtopic.php?f=7&t=93042, hopefully the devs will have a fix for us.

Oh thanks! Great mod! By the way, I've noticed another bug in 1.1, not sure if this is related to the other mod but see the included screenshot :

It happens next to the left of spidertron, it doesn't seems to check the belt direction when it builds the path, not sure if that's the same bug!

I can confirm that 1.1.6 did not fix the issues.
