few crashes with same fatal error

happens usually when i tp out or into a map

"Exception
Fatal error in Metadata/Monsters/PorcupineAnt/PorcupineAntLarge@40:
Number of shared states is different on client and server! Delta: 179"

same error, 3(4?) lost maps due to this.

never happens when i open a map, always later and when TP'ing

these started happen again every now and then

only changing thing is the last number.

i've had delta:99 and 207 and i think delta:210
