We have similar problems, all our alliance stronghold buildings are level 6. Our max wisdom is 60k. After 3 researches, we already ran out of wisdom. It was also due to the ‘smart’ move to increase wisdom with less than 24 hours on the clock. Many team members did donate and had to wait more than a day, before being able to donate more wisdom.
Then we followed one path, but next research was over 50k wisdom. So how any team with our level of alliance building can ever research that? Just by having all members donate their wisdom and then wait for 2 more days. I don’t know but it feels like some strange assumption is made by keenflare about stronghold buildings.
We also went up a layer, from 150 layer to 200 layer. In the previous layer alliance stronghold buildings 6 were more than enough, in layer 200, it’s only enough for the first few resources. We are expected to have 7-8 alliance headquarter there, plus members at least have their buildings at level 6-7 average to donate enough. Some have indeed level 7 buildings, but most have 4-. Then there is no way to do research, even not to keep building headquarters.
And… Make sure that you don’t lose too many wars, since troops also are a problem. For upgrading our headquarter to level 7, 328M is required. Not all teams can afford (better read, only a few) to do that upgrade and then even need more gold to upgrade the 4 other buildings, a level 56 alliance like mine simply can’t afford it.
