I get this error when using the upgrade planner to upgrade a fast miniloader to a turbo mini loader (using Bob's Logistics). The upgrade works but the game crashes when i try to rotate the miniloader. If i place a faster miniloader on a slower one and upgrade manually it does not give me errors when rotating the direction of them.

The mod Miniloader (1.13.1) caused a non-recoverable error.
Please report this error to the mod author.

I get the same problem in the same situation. Using upgrade planner the direction of the miniloader changes, and when trying to rotate it, it gives a similar error. The upgrade was from Fast (red) --> Ultimate (Green), in Bob's Logistics.

The mod Miniloader (1.14.2) caused a non-recoverable error.
Please report this error to the mod author.
