Caravan loading 'Accept' button doesn't work when mechanoid is added

[smallnamespace]

Rimworld version 1.1.2654
What the Hack version 0.5.0.0

Even with a fueled portable charging station that says >0 days fuel remaining, ticking the check mark next to a mechanoid results in the 'Accept' button in the create caravan screen to no-op, so the caravan can't be created.

Removing the mechanoid lets the caravan begin loading. No visible errors or log messages.

Did you also test this with just vanilla, what the hack, and Giddy up to rule out if it's a conflict with another mod?

Yes, I just confirmed with the bare modlist and the issue is still present.

In dev mode I see this stack trace:

Exception filling window for RimWorld.Dialog_FormCaravan: System.NullReferenceException: Object reference not set to an instance of an object at WhatTheHack.Harmony.Dialog_FormCaravan_DoBottomButtons.AddWarnings (RimWorld.Dialog_FormCaravan instance, System.Collections.Generic.List`1[System.String]& warnings) [0x0012f] in <e946ea286bfc48ac9bf712e475d7b9a5>:0 at (wrapper dynamic-method) RimWorld.Dialog_FormCaravan.RimWorld.Dialog_FormCaravan.DoBottomButtons_Patch0(RimWorld.Dialog_FormCaravan,UnityEngine.Rect) at RimWorld.Dialog_FormCaravan.DoWindowContents (UnityEngine.Rect inRect) [0x001f4] in <b9022531d79047b2b6baad3f7d519f01>:0 at Verse.Window.InnerWindowOnGUI (System.Int32 x) [0x00165] in <b9022531d79047b2b6baad3f7d519f01>:0 Verse.Log:Error(String, Boolean) Verse.Window:InnerWindowOnGUI(Int32) UnityEngine.GUI:CallWindowDelegate(WindowFunction, Int32, Int32, GUISkin, Int32, Single, Single, GUIStyle)

I'll look into it when updating the mod to 1.2.

By the way, did you confirm it with the same version of Rimworld you reporting before? I'm asking because 1.2 just released.

[smallnamespace]

Yup, I'd downgraded to 1.1 to double-check.

Btw, this is the first large add-on I've tried over vanilla and it adds a lot of depth to mid-late game. Thanks for continuing to maintain this alongside working on your own game!
