Two faults met while running a dedicated server on Linux (Hetzner, Docker image) with Custom Edition maps copied over from Windows.

Custom maps with capitals in their file name could not be played

cmt_Snow_Grove.map shows in the page's map list as cmt_snow_grove, but adding or playing it failed with:

sv_map: there is no Custom Edition map cmt_snow_grove (custom_maps/cmt_snow_grove.map)

The maps' list lowercases each name, and the rotation's check (map_file in server_rotation.c) then opened custom_maps/cmt_snow_grove.map exactly, which a case-sensitive file system does not have. The game itself loads the map fine, since platform_translate_path already resolves case.

Fix: when the exact spelling isn't there, map_file takes the folder's entry of that name in any case (posix_find_entry_case_insensitive). This covers custom_maps, paths.custom_maps and Custom Edition's own maps folder.

PLAY NOW refused rotation entries with many rules

An entry such as custom_maps\tsce_multiplayerv1:team_slayer+ff=off+team_vehicles=custom+warthogs=4+…+vehicle_respawn_time=60 (about 170 characters) plays fine from the rotation, but PLAY NOW answered:

map is needed (no spaces)

The page sends an entry with rules whole as map, and POST /api/rotation/play read it into 128 bytes, while an entry may be 255 characters.

Fix: the check moves into rotation_play_line, which takes a rotation entry's length (SERVER_ENTRY_TEXT_SIZE), and its message now names the limit. The protocol simulator (tools/server_sim.py) and docs/dedicated_server.md follow.

Nothing the machines send each other changes, so the network version stays.

Testing

• New harness case resolve-case (test_server_rotation.py): a Mixed_Case.map in each of the three folders is listed and resolved by its lowercase name. A negative control (custom-maps-case-sensitive) removes the fallback. It is skipped on case-insensitive file systems (Windows), so the Linux CI job is where it runs.
• New harness case rotation-play (test_server_http.py): a 170-character entry, exactly 255 characters (taken) and 256 (refused, with the limit named), and the old refusals. Negative control play-entries-short puts the 128-byte buffer back.
• Locally on Windows: the two test files went from 161 passing to 164 passing and 1 skipped. server_http.c and server_rotation.c compile cleanly in the Windows build. The other tests that read these files (test_server_toml.py, test_deploy_gametypes.py, test_server_sim.py) fail identically before and after, on Windows-only issues.
• On the live server, renaming the map files to lowercase got around the first fault, and typing sv_map <entry> in the console got around the second.
