Hi! What's the shape of the push volume please?

Shape doesn't seem to matter much. Here's a vmf: https://gist.github.com/Besath/cfc520151c70bc2c87175f813ecfe51a

The reason this is happening is because when you perfectly bhop (like with autobhop) the game doesn't consider you as on the ground because you're leaving the ground again on the same frame - this setting was originally made for jump pads that the player would physically jump on and not bhop over, so it was never a problem in the past.

So unfortunately there does appear to be an unintuitive interaction here, but technically not a bug with how that setting was originally designed, that's why jumping onto the ground within the trigger works but perfectly bhopping through it doesn't.

So the only way to make push triggers work the way I would like them to is to use the CSS approach of combining trigger_push with trigger_multiple and a filter entity which creates inconsistent gameplay while online? That sucks.

By the way, if you walk into a trigger that pushes you high enough, you can keep autobhopping and it will keep working. Some more weirdness I guess.

Another option is to place a trigger_jumpcontrol set to no jumping the same size as the trigger_push, that will prevent the bhop upon touching the ground and allow the push to function normally, I tested this with simulated lag and results are acceptable at 200ms lag and possibly higher - does that resolve the issue?

Oh yeah, that will probably work. Will need to change boost amounts but it may actually be fine. Guess we'll have to wait and see if anyone cries about unreliable boosts again :D Thanks.

One other thing is, making the nojump trigger pretty tall (if the push is small) will help with latency because that's more in air time for the nojump to reach the laggy client and prevent any movement glitchiness when touching the ground!
