Carts (mini cars) carry items around a network of painted paths.
Mods introducing new content into the game.
Augmented or new ways of transporting materials - belts, inserters, pipes!
Is this the problem of Logistic Carts or AAI? https://c.radikal.ru/c10/1906/47/4d0acf64485b.jpg
Can't tell for sure from the screenshot where the bug is. If you can reproduce it and post a save file, happy to investigate further.
The author of AAI has already fixed this error after I told him. The problem was in his mod.
