Entity Animation Controller causing server side crashing in Robot Battle Arena

Partner Rank: 1 (no work around, map not completable/crashing server side)

Partner Team Reporting: Jigarbov Productions

Verification builds: 1.18.10.26 and 1.18.10.27

Summary: Entity Animation Controller causing server side crashing in Robot Battle Arena

Impact: makes Robot Battle Arena 2 uncompletable and results in unhappy players in what is one of jigarbov productions flagship pieces of content. the command crashing the game is a commonly used command and so the reprocussions could be much larger than this one piece of content.

Repro Steps:

1. Open Robot Battle Arena
2. go walk to the npc
3. talk to the robot
4. press a button
5. walk through the tube
6. press "factory"
7. talk to a robot
8. get the "rotator"
9. use the rotator on an area marked by stone brick stairs

Observed Results: The first time used, you might see a shadow of the entity being spawned. Tries after that result in nothing happening and the entity stops spawning, the mechanics that the entity uses are not functional and the game is not completable.

Regression Builds: 1.18.10.20-1.18.10.24 was working

Notes:

I believe this bug is related to the fix noted in the change log of 1.18.10.26 as:

• Fixed animation controller recursion checks from falsely disallowing normal repeat usage of a controller

This particular entity behavior, animation controller and functions have been attached to the report if it helps.
