I have just updated through GOG on macOS (26.5.1) and I’m getting the same error.
No mods installed, removed all config files from ~/Zomboid - no luck.
2026-06-03_23-50_DebugLog.txt
Version: 42.19.0
Mode: Multiplayer
Server settings: Dedicated
Mods: [None that alter tileset]
Save: Inherited from 42.18
Reproduction steps:
1. Take stock in-game clothing (in this example Base.Tshirt_WhiteTINT which curiously renders as very dark grey/brown)
2. Dye tshirt (in this example with bright yellow)
3. Wear tshirt and it appears yellow
4. Drop tshirt and it appears the original dark grey/brown
5. Notice that "local inventory" render shows the bright yellow
6. Other player always sees original color *except* on the "local inventory"
We are also dealing with the same issue on our Dedicated MP 42.19 server. We use mods, but it seems to be a universal issue among dedicated servers, including Vanilla. Here are some of our personal metrics from our 42.18 wipe vs. 42.19. We are also still having issues with duplicating zombies.
