Advanced Placement/Hologram Client Crashes
Closed, ResolvedPublic


As of the earliest build for 1.21 changed to advanced placement seem to result in hard client crashes without any crash logs. This only seems to affect quite a handful of mods, especially some of the top popular mods that utilize this system. The crash seems to appear when ever advanced placement is toggled and the hologram is created. Upon attempting to debug this issue via breakpoints and step through, I can only get as far as the player's command handler, before the game forcefully crashes without any error.

Here are a couple of the mods that are affected:

I have several confirmations from several modders that utilize the same general approach to advanced placement kits, where the placed item is not the same type as the held item. Please look into this before 1.21 launches to stable, as a workaround would be much needed if the core issue does not fit within the development cycle, as we're not able to properly debug this issue with the tools provided.

	override string ProjectionBasedOnParent()
		ItemBase item_in_hands = ItemBase.Cast(m_Player.GetHumanInventory().GetEntityInHands());	
		if (item_in_hands.IsInherited(rag_beehive_kit))
			return "rag_beehive";

		return super.ProjectionBasedOnParent();

This is basically what i'm doing in one of my mods. If i comment it out, the Client does not crash anymore.
I also tried the config entry:

projectionTypename = "rag_beehive";

But it's also crashing Client.

As mentioned in my previous comment, we are working on fixing the issue.
Spamming identical messages of "please fix this bug" will not speed up the process in any way.

@Geez Will you still deploy 1.21 on the 23rd even if no fix for this issue will be found?

@inkihh He said it will be in the stable update, but I personally dislike how it's handled by the Devs, that we cannot properly test our mods for compatibility to prepare for the update. @Geez Something to consider for future updates

@LBmaster this issue fell out of bound of the development cycle due to how late we reported it. In fact this issue existed in the first experimental build of 1.21 but no one tested or reported the issue until it was too late. By the time we reported it, the final experimental update was already approved and was prepped for publishing, and the fix for this was still in internal testing through QA. The timing of this doesn't fall on Bohemia but us for failing to utilize experimental to test our mods.
