I'm currently getting an error during startup. Currently investigating it myself.

Error loading mods

Failed to load mods: auto-barrel__/data.lua:18: attempt to index field "hr_version' (a nil value)

stack traceback:

auto-barrel__/data.lua:18: in main chunk

Mods to be disabled:

:black_circle:auto-barrel (0.2.0)

Disable listed mods

Disable all mods

Restart

Thank you for the feedback, it sounds like a mod compatibility issue, one thing I can do is to write the entity prototype completely from scratch instead of copying stuff.
Can you tell me which mods do you have? You may want to disable some of them to figure out which one causes the issue.

it seems to be a conflict with AAI Loaders

yep, if you install base mod, AAI Loaders, and auto-barrel: this crash occurs:

Thank you for having looked into it, I am currently working on a fix.
Also I'm renaming the topic.

Working fine on my end with AAI Loaders 0.1.4, I'm uploading the 0.3.0 update of my mod right now.
