how to solve this error?

That is almost always caused by the mod miss using mod settings to conditionally include stuff during the data stage. You'll need to contact the mod author and have them fix their mod.

can you just fix it by resync from the server ?

i had to delete my mod folder and download all 1GB of mods again in order to fix it

The problem is the mod is written incorrectly. The mod author has to fix their mod. If I could detect when it happens in a mod I would prevent the mod from loading so mod authors would be forced to fix it.

@Rseding91
Just out of curiosity, what edge case prevents you from checking if the settings are in sync (by mod name+version) *before* comparing mod hashes?
