Updating to report on the current state of these bugs as I have observed them. I play on PS4, on EU-PvP-PrimPlus-CrossArk3 cluster.
Gameplay Bugs
Loot Drops - There was an issue of drops losing their "beam" once they had landed. After patch 541.71, they now retain their "dropping" beam even after landing. Both sky drops and desert crates / sea crates have been working since I started (~August)
Canteen Crafting - No Canteen in my engrams, but I have found canteens from "desert drops" on Ragnarok.
Kibble Consumption - Kibble has worked correctly on everything I have tried. (Haven't tried a Stego or Doed specifically, I will see if I can manage one to test.)
Kibble Crafting - I have cooked most kibbles in cauldron successfully, haven't observed any issues with it.
Coal Harvesting - I have always gotten Coal from obsidian rocks.
Forge Crafting - No issue placing resources in Forge AFAIK.
Mailbox -
Aberration Hazard Suit -
Explorer Notes - Always worked for me on P+. (Interestingly, I remember notes not working a few months ago, on a vanilla server; presumed it was patched at some point, and working ever since.)
Bee Hives - None seem to spawn on Ragnarok. I see them on Island, but have not checked for wild wax or a tamable Queen as of yet.
Aberration Saddles -
S+ Green House Glass -
Harpoon / Tanq Spear Bolt - Haven't tried crafting, but it is available in the list. You can use Organic Polymer, so I assumed the whole approach was intentional?
Lumber Glass Ceiling -
Quality of Life Bugs
Snap Points - Most regular stuff seems okay. This topic probably warrants its own thread, for how many different things could have specific issues. (Here's one: brick dino gates no allowed on platforms, but stone gates are?)
Collision Boxes - Haven't had the doorframe issue since the old pre-launch P+ days. But I did notice that brick sloped roofs at 1x height will obstruct, don't think stone does the same.
Damage Balance (Weapons, Plant X) - Yeah probably ...
Lumber Texture/Mesh Changes - Haven't observed any texture issues on lumber specifically. But some world objects are odd sometimes, notably boreal trees seem to have no trunk texture at all.
Supplemental
Wyverns on Ragnarok - No Wyverns in Scar, or around the "Wyvern Cove" area - BUT Wyverns do spawn inside the southern cave, as do nests and eggs.
Beavers on Ragnarok - No Castoroides or dams anywhere on the map, however the giant dams do spawn reguarly at "Beaver Lake" somehow.
Other Spawns on Ragnarok - No deep-sea spawns at all, in the western trench or northern sea, including Cnidaeria. Jellies do spawn in shallow sea, along with usual creatures.
Spawns on other maps - No overworld spawns of any kind of Island, Center. However, all caves I have checked so far have had regular spawns. (So at least it is possible to get meat and hide ...)
Hope this is helpful.
