Thanks
I was able to reproduce the crash with your save by loading and scrolling up. The game CTDs immediately. From what I can see there are only 4 things that are shown there, a dwarf hauling something, hamster vermin and a dog. Once unpaused also a bunch of flies appear. I ported your game to a -r1 release of Meph's I did a while back and the same game works perfectly fine there. No CTDs when scrolling around. For me its clear that this is a TWBT bug, something messes with the graphics it needs to draw and crashes in the latest build of the plugin.
You can load an older release of the Meph pack using -r1 of dfhack and twbt, there it seems to run. Meanwhile, I will try the latest stable build of dfhack to see if they changed anything.
Update:
I tried moving to DFHack -r3 using the same twbt pulgin but the crash remains, seems to be inherit to the twbt update. I will now try moving twbt from r1 up
Update 2:
Moving -r1 up to -r2 and even -r3 works, please use this file
https://dffd.bay12games.com/file.php?id=15244 and store it in Meph Tileset V5.5 - 47.04\Dwarf Fortress\hack\plugins\, Meph Tileset V5.5 - 47.04\Dwarf Fortress\hack\plugins\twbt\ and Meph Tileset V5.5 - 47.04\Dwarf Fortress\hack\plugins\original\
You will get a warning message when starting the game saying the version was not compiled for this dfhack version but it seems to work just fine.
