Summary

0000047: player position desynchronizes with lowering lift online

Description

Online, a desynchronization of the player position seems to occur when you trigger a linedef that lowers a lift (standard doom lift). The lift lowers, but the player "drops" after it. It's during the drop everything starts to lag/shake. I've included an example WAD. Try to emulate a ping of around 200ms to get a better understanding of what I'm trying to explain.

Steps To Reproduce

Load up my example WAD and emulate some ping.

Client greatly mispredicts its z position if pushed over a ledge by something else

(0000141) unknownna (updater) 2010-09-22 21:01	Yes, if it would have been specific to the 98d alpha builds, I would have stated so in the original report.

(0004516) ZzZombo (reporter) 2012-08-30 08:21	It is still a problem in Zandronum 1.0.

(0005200) unknownna (updater) 2012-10-25 19:19	We can consider this ticket to be a duplicate of 0001079 since we already worked on the prediction there and improved it.
