Mishandled inputs in replay file

[wary drift]

in this game that lasted for 3 rounds, the display for Round 2 in my last game against the player ihatemylif3 glitched into a completely different result upon seeking through the replay by dragging the slider at the start of the game.

behavior persisted after reloading other rounds, but returned to normal after reloading the replay entirely from the Channels page. the resulting desync is consistent when reproducing.

any chance you held down "right" or "left" or whatever key moves the progress replay bar upon starting? if you do that the round can corrupt, if so just exit round->reenter

[wary drift]

i did not hold down either button. this was done using mouse only

[obtuse glacier]

not that then. no clue, have you tried viewing the replay again since?

[wary drift]

yes, i tested both viewing the round again and loading the entire replay again to test if i could reproduce it

[obtuse glacier]

reproduce the corruption?

[wary drift]

yes

[obtuse glacier]

so second time around it was alright

then it's likely just a bug of data not loading and you clicked the round too fast who knows

[wary drift]

the corruption happens for as long as the replay is loaded after it is done

Looks like the somewhat common bug that happens when you watch through a very long round in a replay

the first time you watch the round, everything works fine

but then it bugs out afterwards when rewatching

need to restart client to rewatch it again iirc
