Random crash, unknown cause

[AnnanFay]

Random crash reported as 'Attempt to access invalid address' in log which happened shortly after teleporting in a multiplayer game after opening a chest.

A quick look at the referenced code, searching online, and requesting advice on the Harmony discord makes me think this is going to be impossible to investigate as it's only occured once. Putting the output here as a record, and so the keywords below are search-available.

Triggering line in the mod is:

ValheimCraftingSkill/CraftingSkill/ConfigVariable.cs

Line 26 in 569bb91

return Traverse.Create(backingStore).Property("Value").GetValue<T>();

A similar issue seems to have been encountered before caused by other mods: https://www.reddit.com/r/ModdedValheim/comments/q5yr08/crash_game_crashing_randomly_when_interacting/
