Right after a drop pod raid call.

(There was a mistake in the previous screenshot.)

[Reznal]

I haven't seen that strategy error..

Was this via the Dev tool or just through playing?
If through the Dev tool was it a high point raid?

Pretty sure the inaccessible error is due to the prawn not existing when retrieving by ID

[SirrWilliam]

dev tool - 20 points raid
[RimWorld 1.5] > Execute raid with specifics >Faction > 20 points > ImmediateAttack > CenterDrop

[Reznal]

Ok interesting, I only managed to get it to happen on higher point raids but I also didn't try too many times.

I'm so angry I couldn't use the 🦐 emoji to react to this

This should be entirely a specific debug tool issue, where a debug command is not properly synced.

Tested on branches (07.16.2025 ~20:00 CET):

• mostly 1.6-working (https://github.com/Reznal/Rimworld-Multiplayer/tree/1.6-working)
• little bit dev
• NOT on 1.5

I could not reproduce the error using the following debug options.
I used high points and “drop in center” (if available) to simulate a drop pod raid.

• Execute raid with points...
• Execute raid with faction...
• Execute raid with specifics...

The issue lies entirely with:

Drop pod raid at location...

Reproduce:

• Start two instances locally
• Enable debug mode in Rimworld option and host options
• Open debug menu
• Drop pod raid at location...
• Faction: Hohaya (PirateYttakin)
• 100 pt
• 3 tile radius
• set a target with mouse click
• The other instance should desync, and if the raid pawns have possessions, it should throw the error 'This x is inaccessible,' which is caused by the incorrect syncing attempt.

This debug option is not fully synced. The final step - selecting a target (Targeter.BeginTarget()) - is not synchronized. As a result, the raid only spawns for the person who issued the command, which causes a desync and triggers a code path that tries to sync things via SyncWorker. This is not intended, since only the debug cmds should be synced.

I’ve already implemented the missing debug step. Not sure if I’ll be able to create a PR today -I’ll need to refactor it a bit first and make it more robust. 👍

Nice work! :)
