Hi.
Not sure if this is a bug or intended.
When using this mod the AAI Chaingunner, Flame Tumbler, Warden and Hauler can now only use batteries as fuel.
All other vanilla or modded vehicles I have installed accept both burnable and batteries as fuel.
The AAI vehicles don't define any fuel category. This fine as long as no explicit fuel category is added which this mod does. The fix is to also add the default "chemical" category in this case.
