Hi,
could someone help me with this?

"Error loading mod: Error in assignID: item with name ´heat-shield-tile´ does not exist."

   "auto-research",
   "BigDrills",
   "BigStorageTank",
   "bobassembly",
   "bobenemies",

Just tested, I can start the game without any errors. Did you change any mod settings?

I have all mod settings back to standard and restart.
Unfortunately still the same bug. :-(

No idea what's wrong then. Just in case, you are playing on the latest 1.1 version, right?

Yes. 1.1.26

I have the same version, mods and settings, but get no error on startup. I'm sorry, but I cannot fix it.

RFP works without other mods.
I now activate every single mod and restart.
Let's see if I can figure it out that way.
I'll get back.
Thank you very much for your help!

I have now found out which mod is not compatible with RFP:
"Bob's Metals, Chemicals and Intermediates" -> bobplates 1.1.2
I don't know why that is. Unfortunately, I can't do any more either.
:-(

I can load the mod just fine... I guess you have to play without either RFP or that mod. I'd fix it if I can, but I can't fix an error that doesn't even happen for me.

Unfortunately I have no other choice.
Nevertheless, thank you very much for your efforts!
greetings

can confirm, am getting this error too. latest version, have a lot of Angel's and Bob's mods, and when i remove Bob's Metals, Chemicals, and Intermediates, it works.

update: tested with JUST RFP and Bob's Metals, Chemicals, and Intermediates, and it fails to load. same error as OP.
update 2: deleted the bob's plates patches from the mod folder, and it loads. must be something with that?
update 3: also, some context for the error: it listed Angel's Refining as part of the problem in my crash, so maybe try it with Angel's too?
