Rules (Read this first!)
This is just a template to help you post a useful issue. Erase these rules and any irrelevant categories and content as you see fit.

• Only submit issues related to the latest version of the mod for the currently supported version of Minecraft (which is currently 1.12.2 and 1.16.5).
• When referring to software versions always use the actual version number and never "latest".

If you are opening this for any other reason than to report a bug, it will be closed without explanation! For feature requests, use the feature request template.

Describe the bug
Explore the world with the mod enabled. Game will crash with a stack overflow error. Then you will end up at the multiplayer screen and the world in you single player worlds will be deleted.
To Reproduce
Preemptively generate a world. Install the mod. Wander with a change of an overflow
Screenshots
If applicable, add screenshots to help explain your problem.

Rendering Glitches
Are you using OptiFine (or any equivalent mods that mess with rendering)?
Yes, Optifine G7
Additional context
Add any other context about the problem here.
Biomes o plenty is also installed along with The Abyss Beginnings
Near spawn chunks there are chunk boarders. If you generated world preemptively outside the spawn chunks, then enable the mod, it will smoothly transition the trees with no boarders.
Crashes

• Are you running the latest version of Dynamic Trees? Dynamic Trees 1.16.5 Beta10
• If you are using the DT Biome O' Plenty Add-on do you have the latest version? Biomes O plenty 1.16.5 13.1.0.465
• If you are using the DT Thaumcraft Add-on do you have the latest version? (Currently 1.4.4)

If the above mods are current then please submit a full crash log. The crash log normally contains the names of mods and their versions. Don't be that guy who submitted a crash report without first checking that the versions are current.

Mods List
If your crash log does not contain a list of mods or you have no crash log then please provide a full list of the mods you are using complete with mod versions.
What version of Forge are you running? Forge 1.16.5 36.1.0

After reloading the game the "deleted world" suddenly appears in your world selection again. No clue on what just happened

Please send the crash report (or failing that the logs).

It doesn't sound to me like we could be causing this and we can't determine anything without the crash report anyway. If you or anyone else still experiences this issue please do send the crash report or log if it is being caused by us.
