So I noticed one of my request depots is sending out only 4 trucks at a time for a fluid when there are three fluid depots completely full of that requested fluid and I have 20 trucks in the request depot. Havent touched the settings as such for the depots either.
You have all default values for the mod settings? (both startup and map), you may double check because they've been updated over versions, so we sure start from the same environment
