Unable to host a multiplayer world after update to v0.2.7

[AshlyneS]

After the update to v0.2.7 I am unable to host a multiplayer server because TModloader does not allow it to load due to a version issue.

Issue Description

A thorough description of the problem, including:
Expected behavior: Mod to load
Actual behavior: Does not load
Context: This happened after the update to v0.2.7
Error message (if applicable):

[12:15:15.601] [Main Thread/ERROR] [tML]: An error occurred while loading StarlightRiver v0.2.7

However, you are using tModLoader v2024.3.3.2
The mod(s) have been automatically disabled.
This error was caused by the "StarlightRiver.Content.Bosses.SquidBoss.ArenaActor" class.

Additional context and log files

Add any other context about the problem here.
This only happens when hosting multiplayer.
Fixes I have tried (in order):

1. unsubscribed and resubscribed
2. reinstalled tmodloader and terraria
3. tried making a new character and multiplayer world
4. validating files
5. deleting old versions of the mod in the workshop folder so only the latest is left which is apparently 2023.12 (This doesn't seem like it should be the latest? Is workshop just not downloading the new version?)

Logs: server.log

Update: i have even tried on a different computer. Same issue

This appears to be a cross-mod incompatability. I'll keep this open to investigate further but it appears to have something to do with creating the fake NPC for auroracle's arena during SetDefaults. Perhaps I need to prevent this from running on the server.
