MC uses the client-side position of an entity to determine whether it is inside
the simulation range and therefore whether it will get ticked. For some (most)
entities it interpolates the client-side position to match the server-side one
inside of the tick method... no prices for guessing where this goes wrong.
Somewhat similar to the issue we have with chunk unloads which we work around in
FullReplaySender but worse cause they'll get stuck if they ever leave the sim
range even for a single tick, rather then just when their chunk is unloaded.
