- Fixes relative pathing in mecha_parts_ch.dm
- Fixes relative pathing in bodybag.dm
- Fixes relative pathing in sahoc_ch.dm
- Fixes relative pathing in toys_yw.dm
- Fixes def_zone being defined when only the variable was needed in twohanded_ch.dm
- Fixes relative pathing in trash_pile_vr_ch.dm
- Fixes clip_mask being missing in misc_ch.dm
- Fixes relative pathing in tesh_synth_facemask.dm
- Fixes absolute path being indented in by one (typo?)
- Fixes relative pathing in armor_yw.dm
- Fixes unreachable parent call in audible_scream_ch.dm
- Fixes VERM_LIZARDS being undefined when it wasn't defined, as VERM_LIZARDMEN was the variable being defined + used in mutants.dm
- Removes two un-needed parent calls - these procs have no parent on /obj/structure - thecake_ch.dm
- Fixes invalid kword nano_state in protean_blob.dm
- Fixes relative pathing in drone_manufacturer_unify.dm
- Fixes relative pathing in synx.dm
- Removes arguments of drop_item that don't exist (port was from TG and had force_drop = 1 and src defined.) - vox.dm
- Added vision_required = TRUE to fix proc argument missing - bigdragon_ch.dm
- Added include_robo = TRUE to fix argument missing in demon_ch.dm
- Fixes relative pathing in rakshasa_abilities.dm
- Adds comment to solargrub.dm, unable to fix operator overload error yet.
- Fixes relative pathing in sprite_accessories_extra_ch.dm
- Fixes relative pathing in sprite_accessories_yw.dm
- Fixes relative pathing in phase.dm
- Fixes relative pathing in bluespacecoffee.dm
- Fixes relative pathing in other_ch.dm
- Fixes relative pathing and ambigious ! in living_ch.dm
- Fixes relative pathing in custom_clothes_yw.dm
- Fixes relative pathing in custom_rigs_yw.dm
- Fixes relative pathing in MadokaSpear.dm
- Comments out duplicate #includes in southern_cross.dm as vorestation.dme has them #include'd.
