I came across this bug in a LAN game, but can reproduce it in single player as well. Seems to be savegame-independent.

Build a splitter, mark for deconstruction:

[reserved post for blue belt balancers blueprint code]

These are the balancers for the blue belts, currently only for widths 3 to 16. I might make the larger ones as well, maybe later.

With blue belts the balancers remain mostly the same. Here and there some belts can be removed because of the longer underground sections. The 6, 9, 13 and 14 can ...

And here is the 48-lane balancer:

We all know balancers, but most designs are wider than the belts they balance, which makes them a bit tricky to fit into a factory. To solve this I made a set of inline balancers, only as wide as the number of belts they balance. I thought I might as well drop these here considering the time that ...

Excellent mod! But I never really liked the 'full-color' graphics for the barrels, so I made a set where all the new barrel types are just like regular steel barrels, but with a colored top. Looks a lot cleaner:

Nice one, you beat me to it! :evil:

Over a week ago I fixed this too, but since it was my first attempt at modding mods I wanted to test it some more. I see now that it's exactly the same as your code (except for that typo in the error message that keeps annoying me). Anyway, hat's off to you sir ...
