Greetings Hrogundtir!
Thank you for reporting your situation regarding your struggles with some beasts.
Our team is currently aware of this issue and the workaround is to delete the following file:
Conan Exiles\ConanSandbox\Mods\modlist.txt which will guarantee that mods are not loaded.
In any case, make sure to verify the files of the game and restart you computer after doing so.
Ultimately, if nothing has worked so far, we encourage you to unistall the game, make sure to delete all the game folders and reinstall the game.
Please let us know if the issue persists after performing the suggested steps Hrogundtir.
Thank you for reaching out to us!
