Giant humans?

Today I saw three humans that were twice the size of a giant. They were clearly human due to their distinguishing facial features compared to a giant's.

Just how did they get so tall? Did they use some sort of event item?

From what one of them said, the tin potions are bugged... or perhaps it was intentional?

It's a known bug that happened in Korea at some point apparently. Will probably be fixed next maint

Just a heads up, the other races can get this bug as well. At least, Elves can.

This applies to all races. No Milletian is safe with the threat of Titans
