Not even something simple like oak + dirt drops anything, the manual chop button does not work. Tree grows to full percent and neither a hopper or axe upgrade changes anything, manual chop button does not work, just goes to 100% and stops.

Redstone button restarts the cycle but still makes it stop at 100%

Forge: 1.18.2 - 40.0.48

Im playing a pack with a few friends that we updated recently to 1.18.2 and were having the exact same issue

sadly this issue turns this mod into a decoration only mod.
confirmed using:
1.18.2 - 40.1.0
bonsaitrees3-3.1.0.jar
libnonymous-2.1.0.jar

oddly sometimes they are working (after a server restart) - to be determined if this was a one time glitch or if this is reproducible

We have been experiencing the same thing, however, restarting the server and clients has fixed it for us every time.

issue has been resolved in merged PR:
#305

If you have the time to re-test this issue with the latest version, it would be greatly appreciated.
