I wasnt sure wether to post it here or on TD github.
it crashes on game load.

As it says sth about slimes i tried loading the game with both of your slime mobs deaktivated - still crash.

let me know if this is actually a TD issue.

If I remember correctly this has to do with the experimental summon overlay in my mod. Can you try and disable that in the config and check if it works?

You were right!

I thought changing that setting would have no effect since your summons feature is disabled by default

` # Enable/Disable experimental Summons feature (requires reload)
    B:"Enable (beta) Summons (requires reload)"=false`

Thank you for the quick reply and sorry for the false report :S

Np this is my bad really. The summon feature will probably move to another mod next update.
