Describe the issue
Thrusting does not work on singleplayer.
allowThrusting is set to true in *_server.json located in singleplayer mc instance config folder. thrusting is also enabled, with hotkey set to w but when I try to use it, nothing happens

Additional information
mc version: 1.20
dabr version: beta 2

worked fine on 1.19.4

I'm not able to replicate this issue with the information you provide. Do you have the "Thrust Forward" keybind set, or did you accidentally bind W to "Toggle Thrusting"?

I can't think of anything else that might cause this issue.

yes that was the issue thanks
also can I use thrusting with regular elytra flight?

No, it only works when the mod is enabled.
