yeah, I am just gonna doublepost, hope thats okay..
so concerning Indonesia:
- the traderoute-UP sounds great, but please keep in mind, that if you reduce the AIs willingness to trade resources (which I think you said somewhere) Indonesias 2nd UHV would become a lot harder or you'd have to fight even more (the spawn of Thailand right in that timeframe is already bad enough, imho

)
other:
- what does the Porcelain Tower do now? "All trade routes are counted as foreign and intercontinental" (I remember not understanding it before and you explaining it, but since you changed the trade routes I am confused again. Plus I forgot: "all traderoutes" - all in that city or in all cities?)
- the tech pace feels a bit off, but that might be caused by the Paragon difficulty. When Prussi spawned they were 5-6 techs ahead of me and I am ~2 ahead of everyone else (except the Dutch). Would Prussia actually get the Liberalism-tech if no one had researched it when they spawn?
- a lot of civs, especially the Euros, collapse before their time. without them having lost their core, HRE some time before 1600, Spain ca 1650, England around 1700, etc. However China stayed alive until ~1400 and respawned in ~1525-1550. In this context I have 2 suggestions:
1. I lost a unit I had stationed in a friendly city when that civ collapsed. Can't my unit just be expelled? Seems somewhat unfair
2. Some civs were unstable for quite a while before collapsing, it seems because they simply avoided stability checks. Could you maybe either implement a feature that causes stability checks if you haven't had one in a while (25 turns for example) or that makes them every....10-15 turns if you are unstable? Because you don't always have that spare tech to throw around and see if that civ is already dead or not.
