I could not assign any collection tasks with this mod on. Maybe just incompatibility with Conquest tweaks, will test it out.

Please do! Conquest Tweaks has caused issues in the past, so it would be my first guess too. Possibly the service job income module.
If you can't find the issue, I'd appreciate it if you could share your game log with me - either by copying the text here or sharing the file. You can find your logs in the same place as the "mods" folder, and the most recent one should be "godot.txt".
And of course: many thanks for taking the time to report this issue!
Pro tip: if you decide to share the log here, try formatting it as "Code" with the top-left button in the text box. It makes it a lot easier to read =)
