Problems with item respawn, can anyone help?

[Fussytanuki]

I'm new to modding and am having some trouble with items respawning in the cells I have created/ modified. Any time I test the respawn ingame one of two things will happen: A) After allowing the cell to reset it will crash on load, or B) Harvestable plants will have reset, but if I save and then load the game they revert to being empty again. All items are properly flagged to respawn and I don't have any mods running that influence cell reset rate.
