Forge Version: 36.0.55
Productive Bees Version: 0.6.9.4

I have an advanced hive that if you place down it will spam server console the following:
[15Mar2021 01:13:53.403] [Server thread/WARN] [net.minecraft.entity.EntityType/]: Skipping Entity with id

Note: No entity is specified. My log file is over 200mb from this constantly spamming. It spams this 20 times per second.
I had the area for my beehives chunkloaded before I went to bed. Woke up to server constantly spamming this. I unloaded the chunkloaded area, went to spawn and the spam stopped. I went back to base (spam started) so I broke up each of the advanced hives then spam stopped once more.

This is the beehive in question, causing all the spam. I couldn't capture the entire NBT tags, scrolled off the screen.

It is specifically the ZomBee causing all this chaos. They are invisible. All other beehives with any bee except for the ZomBee do not create the spam. Also, I do not have any clue how I had all my bees transfer into zombee's, they were mostly vanilla. That same bugged hive changed over to all ZomBee's same for my other hives.

Update: Keeping mod. To anyone with same issue, update your server's config to the following until mod author fixes this mod:
Server config location: YourServer\YourWorldName\serverconfig\productivebees-server.toml
Under that file change the boolean value from true to false:
spawnUndeadBees = false

Fixed in 0.6.9.5.
"0.6.9.5
-- Fixed game events not firing causing invisible bees and other issues"

This issue still persists in later version (currently on 0.6.9.9). For example this hive:

When it is placed in the world I get the endless spam in server:

It actually has 3 crystalline bees in it
