I have a lot of mods so I don't know if one of these mods are effecting this but the one of the most recent updates caused the error of "Error while running event Rampant::on_tick (ID 0)
Rampant/libs/TendrilUtils.lua:101: attempt to get length of field 'tendrils' (a nil value)"
Mods I have(all updated): AutoDeconstruct, AutoTrash, Big_Brother, Concreep, Concrete Lamppost, IondicatorsClassic, LoadRedux, Miner Planner, ModuleInserter, Nanobots, Noxys Trees, PickerExtended, SpaceMod, Squek Through, TPtheGreatsFastTreeCUtting, Alien Biomes, Autofill,Cut and paste, even distribution, ore eraser, RSO, Upgrade planner, usefulSpace, and Water fix.
This error only occurred after updating Rampant. Either from the most recent update or second more recent update on my world. It would be a miracle if you figured out what went wrong and fixed this issue.
