con helper crashes on startup

[Bee-Ar]

Describe the bug When using oak dungeon doors option, con helper crashes when starting up

To Reproduce Steps to reproduce the behavior:

1. have the conhelper on at anytime
2. walk into house on build mode OR
3. be in house
4. turn on conhelper

Expected behavior the helper should start once you get the butler to retrieve planks

Additional context here's some logs I found:
