Platform - Windows
Game version - v 1.6.15 build 24356
SMAPI log -
(the issue began occurring at timestamp 22:25:32 ) https://smapi.io/log/2d165bac49f045edaef446ed35b0ca51
Steps to reproduce - 1. Purchase the golden walnut upgrade for the bridge on floor 0 of the Volcano Dungeon on Ginger Island. 2. Leave floor 0 and re-enter.
Expected vs Actual results - Expected result: the Volcano Dungeon entrance map loads, with an added bridge across the first lava block. Actual result: the screen stays black, and cannot be interacted with directly. Attempts to open the menu do nothing.

I purchased the walnut upgrade to add a bridge in the volcano dungeon, but after the upgrade triggered no bridge appeared, and the next time I entered floor 0 of the volcano the map would not load in. I couldn't open the map or interact with the game directly at all once this happened. I had to teleport via the command console elsewhere to be able to do anything. When I skipped floor 0 of the volcano, jumping to floor 1 (debug volcano 1), the mine worked fine, and there were no other issues from floor 1 onward. But any time I re-entered the volcano map for floor 0, whether going into the mine or moving back down from floor 1 the issue reoccurred.

The error message shown on the SMAPI command console is the same every time, and repeats over and over until I teleport away from volcano 0 or close the game.

Checking SMAPI showed an error starting with the line:

An error occurred in the base update loop: NullReferenceException: Object reference not set to an instance of an object. at StardewValley.Locations.VolcanoDungeon.UpdateBridge() in D:\GitlabRunner\builds\Gq5qA5P4\0\ConcernedApe\stardewvalley\Farmer\Farmer\Locations\VolcanoDungeon.cs:line 554​

I have many mods installed and recently updated around 20 of them, though it's unclear whether that caused my issue or not. I followed the basic troubleshooting guide by verifying my game files and restarting the game, but the issue kept happening. I'll probably try removing mods and adding them back one at a time if I don't find a better option soon, but I'm not confident that will fix the issue on my current save file.

If there's a way for me to undo the volcano bridge purchase, that would be great, but I didn't see an obvious way to do so with the debug console commands. Any advice on how to fix this issue is appreciated!

TMXL Map Toolkit might be causing issues. can you remove that mod and all mods dependent on it and see if that fixes your error?

I don't actually have any mods dependent on TMXL Map Toolkit anymore - I guess they all updated to no longer need it at some point? Anyways, I removed the TMXL mod folder and that fixed it, thanks!
