This mod pack using your mod https://mods.factorio.com/mods/primedead/ArumbasAngelBobsfast, i downloaded ur mod, but i have graphics from prototype, the conditional symbol of loader

I just had the exact same problem.

The graphics you are looking for are located in:
\ShinyBob\graphics\entity\add-loader
\ShinyBob\graphics\icons\othermods

So either get ShinyBob or overwrite the graphics in the add-loader itself (worked for me).

I have this ► http://www.cjoint.com/c/GApplmdZ3Mh , but you need to add it yourself in the mod.

i just did overwrite the entity textures, but ingame it is broken.Only thing visible is the small outgoing belt.
Did anything else needed to be adjusted? -the icons work fine though.

i have the same problem as kraftwerk, how did you guys replace the graphics in the add loader mod? cant use latest shinybob cause it breaks the farland modpack

got it working, check this out
