I think that found the alien base must be from interrogation of the aliens. May be capturing an officer, just like x-com. If our soldiers have ranks, why not the aliens? something simple; troop, low-rank officer-high rank officer, and maybe commander.
nope it's not, you need 10 live aliens only for Odd Behaviour research and 3 for Alien mind.
actually this alienbase problem based on probability of it's detection
there is not actually 'trigger' in code to detect it, its depends on multiple parameters:
first y need to have it to be built, it depends on alien interest value which increase in time exponentionally by specific formula, when you will see first supply ships than one base definitely created, after that starts to work periodic check on base detections from CP_CampaignRun function which calls static void CP_CampaignFunctionPeriodicCall, so if by simple language its dynamic check depends on actually stealth value which updates by probability during some period of time, not specificly setted date... more xvi infection less probability for nations (divided by 2) to detect alien base, more supply ships and longer aircraft stays in base area or base in radar range(multiplier 0.4) higher chance to detect it, the most effective way for detecting base is to 'see' by aircraft supply ship landing, it decreases stealth value by 5.0, actually i think problem is in too big decreasing factor for player aircrafts and maybe too high original value, also possible this value for alien bases not saved propetly in savegames...

This list is available at 2.3.1 version? i can´t research the black signaled.
mm if to look date of translations on wiki i think it should be, also based on part of codes i looked think this depends from increasing of alien interest, try to speed up global time and ignore alien ships for 5-6 monthes, me personally waited for 99% of researches till aug 16 2085 until first destroyer ships appeared, for you it can be different.. jan-may 2085 or something like.
Don't CHEAT, please!
