What happened?

Hello, I updated to version 2.4.21c and I no longer have CreaturePlus mobs, in the console instead I have Error every time one of the 2 mobs should Spawn.

Steps to reproduce the issue

• You just have to have the Addon creaturesplus installed and roam around a world at night to normally spawn them and errors occur in the console each time one of the 2 mobs should appear.
• Another solution to get the error, use mob eggs: . Drunk . Glow Squid . Brush Stooge

I just installed version 2.4.21b and there the mobs of "creature plus" do not spawn but the eggs of "creature plus" no longer work at all to spawn they eat each other. So no more errors in the console but no more mobs or eggs that work from Creature anymore! This is why I had not seen that the problem existed from this version 2.4.21b I had not been to see if the 3 mobs that I use with spawner

[vdl19]

I just reverted to version 2.4.20 and creature plus mobs are now working again without error. I did not put back the modifications that had to be made when we go to 2.4.21b and c I hope this is not a problem because otherwise it will take a bit long to recover the files from before.
