Lua type mismatch on some gallery IDs

[jcdenton-unatco]

Warrior sometimes fails to download from nhentai, with this output in the logs:

This line stands out:

Lua runtime error: nhentai.lua:399: Gallery IDs do not match. Got 498281, expected 498281.

Those IDs look the same to me. Maybe Lua accidentally converted one of them to a string/number? I'm not sure why the script fails on some galleries, but works fine on most.
