Third Seal counter bug when transferring to Undying
When running Third Seal and Undying, if Third Seal is cleansed first, the counter will appear to reset although the survivors will correctly remain blind.
Steps to recreate:
1) Start a game as killer with Hex: Third Seal and Hex: Undying.
2) Injure one or more survivors to apply Third Seal.
3) Have a survivor cleanse your Third Seal. If Undying is cleansed first, the bug won't occur.
4) Third Seal will appear to lose its counter, although the survivors remain blind. If you hit survivors again, the counter will count up again as though you're re-blinding them.
Unsure if it's relevant, but from the survivor perspective you can see a single frame without a hex debuff after cleansing Third Seal. Perspective from both sides is provided in the attached video.
