Exotic birds throwing errors all over the place

I use newest sponge forge 1.12.2-2838-7.3.0
And i have newest Exotic+Birds+1.12.2-3.2.0
I get this error every time i break a block under a nest.

Nests spawn on tress everywhere
people on the server break the trees obviously
every error causes quite a bit of lag.
Plz help
