commit 0a61781b99
Author: FaceDeer <derksenmobile@gmail.com>
Date:   Mon Aug 1 14:50:07 2022 -0600

    add an additional check to ensure old timers don't cause inappropriate growth

commit 1d7b6010c3
Author: FaceDeer <derksenmobile@gmail.com>
Date:   Mon Aug 1 13:21:29 2022 -0600

    stop timers when seeds are picked up

commit c8fa25ccd7
Author: FaceDeer <derksenmobile@gmail.com>
Date:   Mon Aug 1 13:05:24 2022 -0600

    fix replacements for dwarven syrup taffy recipe

commit 4de45bb6d7
Author: FaceDeer <derksenmobile@gmail.com>
Date:   Mon Aug 1 11:09:48 2022 -0600

    account for some additional mod dependencies

commit 83ea06bbaa
Author: FaceDeer <derksenmobile@gmail.com>
Date:   Mon Aug 1 11:09:14 2022 -0600

    update cooking recipes to be more specific.

commit 302da3ec51
Author: FaceDeer <derksenmobile@gmail.com>
Date:   Fri Jul 29 17:12:59 2022 -0600

    add location logging for debugging purposes

commit 11667e184e
Author: FaceDeer <derksenmobile@gmail.com>
Date:   Sun Jul 24 16:54:21 2022 -0600

    add checks for submods being present

    the df_trees and df_farming checks are likely redundant, but if primordial layers are disabled someone might not have df_primordial_items installed.

commit 5906308d87
Author: FaceDeer <derksenmobile@gmail.com>
Date:   Sun Jul 24 16:49:23 2022 -0600

    add config settings for biome restrictions, vastly reduce copy and paste in code

commit e52820c282
Author: FaceDeer <derksenmobile@gmail.com>
Date:   Sat Jul 23 20:45:26 2022 -0600

    add initial stab at growing conditions - biome restrictions for trees

commit 7b99556df9
Author: FaceDeer <derksenmobile@gmail.com>
Date:   Sat Jul 23 12:08:41 2022 -0600

    adding biome API. Not yet tested.

commit bf82b3b3fe
Author: FaceDeer <derksenmobile@gmail.com>
Date:   Fri Jul 22 21:22:37 2022 -0600

    added stubs for growth permission for farming plants

commit 46765df3ef
Author: FaceDeer <derksenmobile@gmail.com>
Date:   Fri Jul 22 18:36:45 2022 -0600

    initial work for restricted plant growth. split out growth conditions for trees, and reworked torchspine to not use ABMs while I was at it.
