As many are already likely aware of Texas has had this handy little research tool available here; http://nsdossier.texasregion.net/
Within it's history section it allows one to search the long term histories of individual nations.
Very helpful, in many regards, and it fairly obvious for why I need a tool like this, sadly however it no longer dates back to 2003ish, but only to the end of 2015... 12 years missing.
At this point it seems unclear when or if it will return fully, I wanna reach out to the technical savvy to see if there are any similar tools out there available or encourage someone with technical knowledge to help Texas. Or best and most unlikely encourage technical mods to add something like this as an in-game feature.
