I don't know if other people are having this problem but in the latest experimental branch of the .44.02 starter pack if you install a tileset you cant build pedestals and any attempt to make a display case it just makes mortars. Everything works properly in a fresh install of 44.02 but as soon as I attempt to install a tileset it will have the same issue but then when I attempt to switch to ascii it will tell me it cant update the savegame because its corrupted.
I imagine its because none of the graphics sets have a sprite for pedestals/display cases but if you go back to ascii the raws stay corrupted even if you generate a new world.
Sorry about that. In version 0.44.02-r02 of the Starter Pack only ASCII, CLA, Dungeonset, Mayday, and Phoebus support the pedestals and display cases.
I'm not an expert how this stuff works, but if you want to try to fix one of your save files, you might try making a backup of your save file and installing the /raw/objects/item_tool.txt from the CLA, Phoebus, or the vanilla version of the game into your save file. It would probably be a good idea to place it into /Dwarf Fortress v0.44.02/raw/objects/ folder too. That could possibly make the pedestals and display cases craftable in your save file, but sometimes stuff doesn't work when you add it after generating the world.
Ironhand, Spacefox, and Obsidian will probably all get support soon. I think this they'll all be fixed in the upcoming 0.44.02-r03 version of the Starter Pack if you just want to wait it out.
Thanks for the tip on drawing sprites for the pedestal and display case. I will look into that. There might not be room for new sprites on the main tilesheet. I'm not sure if TWBT overrides work with "item_tools" such as the pedestal and display case. But we should at least be able to pick more appropriate sprites from the existing sprites main tilesheet.
