Summary0000047: player position desynchronizes with lowering lift online
DescriptionOnline, 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 ReproduceLoad up my example WAD and emulate some ping.

Just to double check that this isn't caused by any of the crouching changes: This also happens in 98c, right?

Yes, if it would have been specific to the 98d alpha builds, I would have stated so in the original report.

It is still a problem in Zandronum 1.0.

We can consider this ticket to be a duplicate of 0001079 since we already worked on the prediction there and improved it.
