There are a lot of errors I fix, but no matter how many I fix my focus tree never improves. I want to see if these errors (from the debug mode page) can hint to what the errors are.

How do I fix these types of errors?

Also I don't think they have much to do with my focus tree

"no random ideology available for group Despotic" (in any ideology) means that all of your types e.g. "Autocratic Monarchism" have been set to "Cannot be randomly chosen"

The game requires at least 1 type to be available should a country happen to find itself in that ideology (e.g. if an Autocratic Monarchism nation puppets another).

"Unexpected token: faction_trade_opinion_factor" was an issue with the exporter not putting faction-specific modifiers in the right scope. This should now be resolved.

"invalid database object for effect/trigger:  file: common/modifiers/00_static_modifiers.txt" - You will need to copy the file mentioned from the base game, and add it to your mod. Then remove anything which references the base game's ideologies (Search for #LaR Compliance and remove everything below it)

"invalid database object for effect/trigger:  file: common/ideas/_economic.txt" - As above. But you will want to change the base game ideologies to your own so that they can pick their economy law.

"invalid database object for effect/trigger:  file: common/ideas/_manpower.txt" - Same as above, but for manpower.

For all the other country ones, e.g. "Error: "Unknown modifier: democratic_drift, near line: 384" in file: "common/ideas/australia.txt"", if your mod completely overwrites all existing countries. I'd just copy every idea file from the base game, and empty it. (Meaning you'll have 195, including generic, empty files in your mod). If you don't overwrite that nation, then you'll need to edit the ideologies inside that file.

Also, if you are removing all base-game countries, I'd copy the files from "common/country_tags" and empty those too (so you don't have base-game nations claiming land, causing resistance, and potentially being puppeted)
