Auto queue + missing crafters = nil dereference

Support Other Reports
#1

Summary:
With auto-queueing enabled, if you try to start construction of a building without having all the needed crafters (for instance, the building requires cloth but you have no weaver), a nil exception will be thrown, construction on the house ceases, and the house becomes impossible to complete.

Steps to reproduce:

  1. Enable auto-queue crafting for building.
  2. Do NOT assign all needed crafters for a building.
  3. Try to build the building.

Expected Results:
The building should not be queued, or should be queued up without the requirements being queued up.

Actual Results:
Nil dereference and stuck construction.

@no_io which Stonehearth version are you playing?
I can’t get this to reproduce on latest A18 (3107). The building is built, but the missing objects for the missing crafters are on ghost mode until I get them (by crafting / buying / looting them).

Hm. I thought it was trivial to reproduce. Let me play with it for a bit and try to get a save game which demonstrates it.

You’re right - I can’t get it to trivially reproduce on release-610 or develop-3109. Apologies. I will post the save file if I can get it to happen again.

Thanks. Will tag this as not_reproducible. If you get it again, please revive this thread :slight_smile:
