As title says - Maple, paperbark and cinnamon trees have no collision on their logs, allowing you to walk through them.
Also they like to grow in the ground - When they try to grow a 1 or 2 block tall variant, they forget to remove the bottom logs from the 3 tall variant, wedging them in the dirt instead.
Do I expect you to update the 1.19 version with this fix? I'd appreciate it but I'm not holding my breath. Mostly I'm just worried this hasn't been fixed in newer versions as I saw no mention of it in the changelogs (Haha, change logs).
