I have problem with DLC's in moded kerbals

[urban imp]

I'll send list of mods at the afternoon

[urban imp]

so these are my mods

[unkempt heart]

So I'm not familiar with Reviva, the two ASET mods, nor custom barn kit (which is probably a dependency of I don't know what other mods)
You can try temporarily removing those see if it fixes the problem.

If not, another thing you can try is 'verify files' from Steam, GOG or wherever you got the game, in case a corruption snuck in.

I thing that I havent it before I add reviva but I will try it

[urban imp]

maybe it will be that integrity becose after I verify it it start downloading some files
