`gps.tileset.texture_indices`
version tracking 50.09->50.10 gave a putative reference match of 50.09 gps.tileset.texture_indices[5379] with 50.10 gps.tileset.texture.indices[5487]. this strongly implies that 50.10 added 108 elements to indices
since gps is currently misaligned in 50.10 (gps: DF: 222560 | DFHack: 222128 per @lethosor), adjusting indices so it has 108 more elements than were present in 50.09 seems appropriate
additionally, i've found a putative reference match of 50.09 gps.tileset.texture_indices2[7774] with 50.10 gps.tileset.texture_indices2[7810] so that suggests that texture_indices2 should be extended by 36 entries
and now 50.09 gps.tileset.texture_indices4[5379] has a putative reference match with 50.10 gps.tileset.texture_indices4[5487] suggesting that texture_indices4 should be extended by 8 entries
stale; has been resolved by other means
