Research technologies costs; where did my orcs go?

[coloringdede]

I am trying to find a chart of all the research tree technology costs. Specifically the costs for Chapter 15 for technologies that I have already researched.
I have lost a lot of orcs and I am trying to figure out if I ignored the cost of a research technology and it required a bunch of orcs or if I lost them in the spire (I don't think this is likely.

Maybe a better way for me to discover this is a place where I can look that orcs are required to "play".

Many Thanks

I constantly miss the wonder upgrades. Did you push one of those through, maybe? My next GA upgrade takes 265k orcs.

Here is the link to Elvengems and scroll down to COSTS AND REQUIREMENTS and FYI ch 15 uses 187,000 orcs
