Sorry about missing that last part - yes, LOC is short for Localization. That forum is mostly for reporting misspellings, bad grammar, misleading word choices (that were not intended as deliberate misinformation), etc.

However, things that result in bad consistency of lore or bad continuity are also "text bugs". If the inconsistency is unintended and English-exclusive, they'll just nuke it and phrase it better. However, Koji Fox is more or less the top of the localization totem pole and works closely with world lore head Banri Oda, so if the lore at large is broken somewhere, the LOC team will just keep passing it up the chain until it gets to someone who can fix it. Sometimes an update hits all 4 languages at once later on.
