This has the nasty effect that e.g. several major naval bases are no longer on the map if you don't change their ids accordingly.
That's true, it might be a problem I haven't thought of. On the first glance everything looks fine but yeah there are probably some provinces missing installations and others having installations they shouldn't have.
Just to name Oran, Toulon and Alexandria, which have got new ids. And there were several more.
The CORE devs plan to adapt their mod to AOD. Then they'll be able to make use of the brigaded ships. If you're adapting E3-CORE to AOD you can implement these already now, although cross-checking and changing the naval units will take some time. Keep in mind to add the brigades and to check the techs, if they're activated correctly.
Another issue is that CORE uses a slightly different resource system where some provinces have negative resources (to simulate consumption). Switching the map to E3 cancels this neat feature unless someone goes through the trouble of adapting the CORE resource distribution to the E3 map, which would be a ton of work I suspect.
Yes, fixing the resource distribution will cost you many, many hours...
Maybe we should break up this task of modifying the province.csv in several parts:
checking/correcting the names of regions and areas
checking/correcting the status of infrastructure
checking/correcting the distribution of IC
checking/correcting the distribution of resources
This is needed to play vanilla AOD on the E3 map. In addition to this you have to do for E3-CORE:
checking/correcting the distribution of IC
checking/correcting the distribution of resources (including negative resources)
The real question remains how far has he got cross-checking and adapting the CORE events to the E3 map?
For the most part everything seems ok. Of course, I haven't played through every possible event sequence, but the default ones work.
I'm currently playtesting the CORE2 scenario on the E3 map and only a few events slightly malfunctioned. For example, the Munich agreement transferred all Sudeten provinces to Germany but one, so I've quickly fixed that.
There are many more events which have province ownership as a trigger or add/remove provinces/cores I can tell you. Since CORE is an on-going project you'll have to check the event files after each update.
Do you have any ideas about the cause of the warning upon loading the scenario that it contains errors, or how to track it down? It's the biggest problem I see right now.
Errors which cause a general warning at the end of the loading sequence of a new scenario seem to be mostly inconsistencies. E.g. misplaced units. Most errors give a separate warning so that you can correct the bug quite easily. If you have errors you have to check all your scenario files. Simply because of this I have offered you to use my adapted scenario files which I have checked thoroughly. You can simply copy the CORE OOB into these files. Then you'd have to cross-check the locations of the units. Misplaced Divisions are obviously harmless and can - thanks to nofog - easily be spotted, but misplaced planes and ships cause errors.
