This page is kept up-to-date with all the stuff that I'm aware of is not working correctly in the app.
If it's not mentioned here, please let me know via the Discord what's bugging you!
Sixth-Pick tracking doesn't work in the first round
In the first round, sixth-pick tracking can be erroneously assigned to the wrong player/Operator.
This is caused by a mismatch in "timing". Basically, if the Operator Banning phase goes quicker than expected (all 5 teammates vote on same Operator in quick succession) the app is unsure exactly when the Sixth-Pick phase begins.
Unfortunately, until Overwolf allows for more granular phase detection (e.g. "Operator Ban Phase", "Operator Selection Phase", "Opeator Reveal Phase", "Operator Sixth Pick Phase"), this is impossible to solve reliably.
Wrong Plant Detection
In very rare instances, the app tracks a defuser plant when this is not the case.
From testing, this occurs when an attacking player "locates" both bombs within 25ms of eachother (either by walking into site, or by droning into site) during the Action Phase.
I'm looking into ways to counteract this rare issue.
