When attempting to boot up the game, the following message appears.
Failed to load mods: File ultimateCore/graphics/ufp_icons/ufp_he3-he3-rocket.png not found
I have removed all other mods. Attempting to place a properly named PNG in that folder did not fix the issue, though I have no doubt I did something wrong there.

Actually as an edit it did fix the issue. Turns out it just shifted the issue down to ufp_rocket_recipe.png also being missing. I am going to guess that the ultimate core mod has not yet been updated.

i will take a look. Edit: i just forgot to update the requisites and upload ultimatecore, remove and dl the latest version of ufp, should work

Unfortunately I get an error message when starting with this mod.

Error loading mods: File_ultimateCore__/graphics/ufp_icons/upf_group.png not found
Mods that need to be disabled:
ufpFixed (1.0.5)
Reset mod settings

yea, in fact i reworked all graphics, some stuff had wrong names, just finishing next release of UFP and it will work

many thanks for the quick response

version 1.0.7 should be working, added fusion ammo!
