hello there.
updated my game to 1.1. 69, and when i loaded the map, all miniloaders that were configured to split sides of belts with different items just started outputting the same on both sides. obviously a problem when you have hundreds of grids with that design ;)
when checking a miniloder, the split lane was unticked, and the same item was set in the whitelist on all 3 settings (left/middle/right)
interestingly the item in the whitelist was not the item loaded onto the belts, it was the item "missing" from the config.
I reverted to 1.1.68 and reloaded the save and everything was ok again.
Perhaps a good idea for miniloder users to not update beyond 1.1.68
