(Build 9269) game crashed when killing zombies atop of chair

so in experimental build 9269, using MSX Deadpeople tileset, im just walking around the city until i found a FEMA camp, i decided to loot the camp but didn’t expect so many zombies inside so i got overwhelmed and has to defend myself using golf stick. and then the game crashed after i killed a zombie that is sitting on top of chair tile.

i can’t get a screenshot of the error but i remember the error log says st12system_error.

tileset handling problem or development bug?
