Happens when trying to ignite a portal to the cloudlands, but the cloudlands mod hasn't inited yet because it hasn't needed to generate any islands:
ServerError: AsyncErr: ServerThread::run Lua: Runtime error from mod 'default' in callback item_OnPlace(): ...\minetest-5 latest\bin\..\mods\cloudlands/cloudlands.lua:591: attempt to index upvalue 'noise_heightMap' (a nil value)

Soon the nether mod will provide a portalstone, and cloudlands:ancient_portalstone will become an alias of that, so I'll reduce the amount of this that is being created in the Nether. Since 82d4283 ancient_portalstone is available from the islands anyway.

because the giant trees are cool... and too rare. Default rarity for schematic-based objects such as trees and ancient portals can be changed without causing any chunk boundary generation mismatches.

register_alias_force() can cause get_content_id() to throw an error, under circumstances I don't yet fully understand. This change should prevent get_content_id() being invoked on aliases.
5.2.0 removes the file_exists() helper function, and get_content_id() now throws an exception if the node isn't found (instead of returning minetest.CONTENT_IGNORE)
This will cause it to run slower in biomes with dust, due to needing an extra vm:get_data() and vm:set_data(), but prevents the dust nodes from interfering with decorations (e.g. snow preventing tree growth). In native mapgens the dust is applied last, falling on top of the highest nodes.
