UPDATE:
- Twigs, bird_egg (Penguins) and tallbird_egg no longer auto stack when spawned by the world. Penguins would keep spawning them, because they want to have more than one next to each other, leaving behind 30-40 eggs that would turn into piles of Rotten Egg lying all over the place.
-- Related to this, I removed the Twiggy-tree option, since it makes more sense to just exclude Twigs from world-auto-stacking in general to solve the problem.

- Modders can now use four special tags to exclude their items from specific parts of this mod:
-- "no_autostack_all" - makes the mod completely ignore them.
-- "no_autostack_w" - the mod doesn't automatically stack them when spawned.
-- "no_autostack_m" - the mod doesn't automatically stack them when dropped.
-- "no_autopickup" - the mod doesn't try to automatically pick them up when spawned.

- The mod now ignores all traps.

- Fixed another crash when attempting to access Physics on an object with no Physics.

There has been some trouble with a few other mods making a bunch of things stackable without actually providing proper code for them to function as stackables, making this mod stack a bunch of things which do not work properly afterwards. Fixing this on my end is not feasible.

HOWEVER, I have implemented a fix for the most prominent problems, which were things with a "heavyobstaclephysics" component, which are the things you can pick up and carry around e.g. glass spikes/castles, and a more specific fix for the sand spikes/castles.

I'm going to stop there with the special checks, because it will get out of hand. These two checks are benign and make sense, as heavy obstacles should never be stackable anyway, and the "groundspike" tag is unique to those two prefabs, so it shouldn't mess anything else up.

Thanks for all the feedback! And thanks for the community awards and 5 stars! I'm honored <3

- Made a separate setting to turn off world auto stacking for Twigs spawned close to Twiggy Trees. Twiggy Trees are special, in that they spawn some Twigs every growth cycle, but ONLY if there are not already two stacks of Twigs on the ground close to them. If you turn this setting on, they will end up creating a full stack of Twigs, but if you keep it turned off, the Twiggy Trees should work as intended by the developers, leaving only two stacks of 1 Twigs each.

- Made mod ignore any entity with a locomotor (movement controller) on it. If the entity is supposed to move around on its own after spawning, then it should not qualify for automatic stacking or pick up. One example is Mushtree spores.

- Fixed crash when fishing.
- Optimized world initialization performance by skipping any items that are in containers or in a player's inventory.

- No longer automatically picks up items which are on fire.
