So not actually sure if this is a 18.14 or an 18.13 thing, or perhaps even an issue at my end! But after loading up today....
1st issue: I've noticed I can no longer manually craft anything from this mod, as there is no longer a creative mod tab of items in the character window. My guess is a bug related to the UI changes. i.e. If I open the Character UI on the Crafting menu, I have the 4 standard tabs, Logistics, Production, Intermediate Products and Combat, but the creative tab that was there before 18.13 is now gone.
Note: I had a couple of Creative provider chests already built and set to group 2 (creative items), and I can get at all the creative items from the chest. So I know the mod is still active (and can use this as a work around for now). I can also use Q to pick existing creative items on the map, and drop those down, and this does also generate a full stack of those items in my inventory, as expected.
2nd issue. Fluid sources no longer have any recipes (so no oil, water etc). I can copy and paste recipes from existing Fluid sources, but this means I can only use Oil and water currently, as those are the only two I have on my current map (I've been designing a new late game Oil processing plant).
For ref:
Game version 18.14 (Steam)
Mods: base + Creative mod + Bottleneck
Game scenario: Sandbox (not freeplay)
If you need anything more, let me know! (Couldn't see any errors in the logs).
Cheers!
