Noticed that Intelligence and Intellect were used interchangeably in French, which was confusing. Fixed that, leaving only the word that was used more already. Found same issue in Polish and Korean, fixed it same way.
Bugfixes
In Youtube videos, I noticed a bug that I never reproduced: some strings weren't found in localization, even though they are definitely present.
I have implemented a fast workaround for card names, but the bug kept happening for "Normal" in French, for example.
Looks like what all these cases have in common, is that the word is spelled exactly the same in both languages, English and the other one.
For card names for example, there's a pattern that governs order of words in card name, which in most languages looks like "{0} {1}", And in those languages, this diddn't localize properly for many players.
Another weird thing is, that the bug is gone once you switched to English and back. I have added a forced switch to English on first game start (when Language Screen is shown), as one measure that'd hopefully help newcomers.
But to fix it for everyone, for now in case a string isn't found in localization, I take it from English. Which fixes the bug, and (supposedly) would only cause issues for strings are actually muissing (which would be a bigger issue in itself).
Thank you for understanding. Being unable to reproduce this issue, I am fixing it blindly. Asked on Unreal forums about this issue. Maybe they'd tell me why this issue happens.
