Y capped during uber cannon launch

I built a TNT cannon with 80 focused charges. When firing at an angle of 45ยบ i blasted off to approximately y=620, at which point my character acted like if it hit a solid ceiling, sliding sideways and falling. When i used half charge, i blasted off normally and hit a vector of y:1059,5.

Then i built a larger cannon with 160 charges, at which the full-blast cap was seemingly reduced to approximately y=310. Character instantly hits this height and slides parallel to the ground until coming to a halt and falling to the ground approximately 500m away from the cannon.

I attached a scheme of the observed trajectory. On multiplayer, all that happens is that after (latency) milliseconds the player is teleported back to the explosion origin with a speed of zero like if it never happened.

Please force a crash by pressing F3 + C for 10 seconds while ingame and attach the crash report here.

Attached crash report during fire, and crash report after firing. Do you want me to attach the map with the loaded cannon? It's 1.9 MB.

I went up and up and up and up...
Never stopped until I started to go down. I went really far from the cannon though.

I didn't abruptly stop either. Just kept going.
Nice cannon though. Good job.

Shot height and width is quite inconsistent.
Depending on the standing point when shot i flew up to > 700, see screenshot

Thanks ๐Ÿ™‚

I gave it another shot just to be sure, was capped at y:372.

News. I finally understood what happens; These shots have an oblique launch angle, so the player hits unloaded chunks. Due to the new mechanic implemented to avoid teleported players falling into the void, the Y speed is discarded when they exit the loaded area. As soon as the chunks load, the player then falls with gravity.

So i believe this is working as intended ๐Ÿ™‚

Uploaded the correct trajectory diagram.

Thanks for the update, resolving as intended.
