|Target Version||Fixed in Version|
|Summary||0004637: the ping reported by GetPlayerInfo depends on the local game speed (desync when gadgets use this)|
|Description||When watching a replay of a game, the ping reported by Spring.GetPlayerInfo() varies depending on the gamespeed at which the replay is being watched. Spring.GetPlayerInfo() is a synced read and this is a potential cause of desyncs.|
|Steps To Reproduce||See the attached demo - playerID 7 starts to lag out within the first minute and 60 seconds into the game his ping should be around 30 seconds. When the demo is watched at speed 1.0, this is the case. When the demo is watched at a higher speed (e.g. 2.0) the ping reported is much less. |
The issue cannot be reproduced using /skip, the game speed must be explicitly changed (alt -/+).
|Additional Information||Note that the attached demo will desync if watched at speed != 1.0, for the reason described above, when the lagging player should get taken around 1.04 minutes. BA includes the cmd_idle_players gadget which judges a players idle status (and, correspondingly, it they are takeable) dependent upon ping and other factors.|

the issue here is imo that player ping is synced, it should be unsynced.
nice finding, thanks!

Player ping should be synced as far as I can see - it should be the ping that was recorded from that player while the game was in progress, and it should have nothing to do with the speed at which the game was played/re-played (which is unsynced because of replays).
