L_mission.odr doesnt work properly

[dragonslayer619]

When i edit the bounties..... dont show properly in game

maybe could be a bug

If you open the file and the changes were there, then there's no bug. The editor worked exactly as it should have.
Whether the game reads or like your changes is out-of-scope of this project and not a bug (so long as the file is formatted correctly on save, which, if the editor can load it a second time, probably is).

PS: Saving changes as json does not alter the original file! You have to actually press save separately from that. Read the wiki for more.
(If you're using -unlock and adding rows none of that is supported in the json export to begin with.)

PPS: Make sure you have the file in the right path: Monster Hunter World\nativePC\common\facility\l_mission.odr
