The sprite_remove in Sprite.cpp tries to find itself inside the quadrant.
It does not find itself, and because the rest of the code assumes that it will always find it
The normal code tries to set the value of the next_in_quadrant so that whoever points at it, will now point at its next sprite.
But because it didn't find whoever was pointing to it, it would set the pointer to SPRITE_INDEX_NULL to its next sprite.
This would lead to cycles in the linked list
The reason that the sprite was not found is that during the entry of a ride, the position of a peep is set to LOCATION_NULL
Exiting a ride sets it back to whatever the location is of an exit.
However stopping a ride that still has people in it would go wrong, as the people are removed from the ride through ride_remove_peeps
This function was called during the PaintWindows.
The fact that this function is called during the painting is the problem, because of the tweening:
Before painting all the positions are stored (Which would at that point be the LOCATION_NULL), during the painting
the peep would be removed from the ride, setting their location to the enrance/exit
After painting is done all the positions are restored again, so the patched position is forgotten and then it would be
removing a sprite with location LOCATION_NULL and that goes wrong
The fix is to have the window update outside of paint
Enable gzip, but only for local save, as GitHub will accept
gzip-compressed files even if they don't advertise it explicitly. Update
changelog and GitHub issue template to reflect that.
