Unfortunately I know of no workaround for that issue and the only way to avoid the crash is to take out that part for the moment. (Which comes with the drawback that Zeus could kill all bad guys instantly and the entity list being filled up)
Other than that we need to hope for a quick fix from BI.

@bgromis:
Can you check if you find the command "removeCuratorEditableObjects" used somewhere in your Code?
Thanks to your crashdumps I identified a bug in that routine (filed in T127571) that causes Zeus players to crash.
Unfortunately I had to make the report private since it contains in-depth details and could be used by trolls to crash Zeus players (that are most likely also admins).
I can only offer you this video reproducing the crash on a vanilla server: https://youtu.be/T2JNvxV6zYE (clumsy is just a tool that simulates network delay)
