Bartershoess: Stats page still shows red levelup arrow after applying stat increases,and later stats have reverted to starting stats.
Are you sure you applied the stat point distribution, by clicking on the checkmark button at the bottom of the stats window? At lower screen resolutions especially, it might be hidden behind the UI toolbar at the bottom of the screen.
Once you confirm the distribution of all unused stat points, the arrow on the stat icon should be removed.
There is a bug with distributing stat points but not confirming them; after saving and reloading they will be lost. There is a save editor which can be used to fix that, though.
How to spend stat points?
