I got the following error when attempting to load the mod.

0.748 Mods to disable:Failed to load mods: core/lualib/dataloader.lua:13: Invalid prototype array {}
stack traceback:
[C]: in function 'error'
core/lualib/dataloader.lua:13: in function 'extend'
MultipleUnitTrainControl/settings-updates.lua:38: in main chunk

Mods to be disabled:
• MultipleUnitTrainControl (0.4.10)

This is probably a function of the other mods you have installed, since MUTC searches for locomotives to modify. Can you post the factorio log file produced when this happens?

This is the log of the failure:

Thank you !

I think I know what is wrong. I bet it will work if you install "Electronic Factorio Extended Locomotives" in addition to MUTC. When I added compatibility with More Electronic... I didn't test it with just the basic Electronic installed.

I'll take a look at fixing it tonight.

Fixed in MUTC version 0.4.11. Thanks for reporting the bug!

No, thank you for shuch a quick response!
