Vexes have attacking and animation problems

Vexes behave normally and attack very aggressively on Legacy Console and Java versions, but they’ve got a few problems on Bedrock. Firstly, when hostile, they hold their sword with two hands and, when attacking, they still put the sword holding arm back like a vindicator, but the other arm remains in a strange looking position. They behaviour is really weird too - rather then aggressively charging at the enemy they just bob up and down through floors until they reach the enemy and attack them
