Extraction speed and excavation speed. Do they work?

[Parritron]

I have tried to add the improvements in digging speed to my five expedition centers and extraction speed to my five fossil centers. I occupy the three slots per building. At 10% speed per upgrade, 30% per island and should go 150% faster in total since improvements such as increased fossil center capacity are cumulative on all islands. However, I do not notice any increase in speed. The excavation sites continue taking 2-3 minutes and the extraction speed 30 seconds.

Have you tried it? Is it a game error? A priori and personal experience seems a failure of the game.

I can't say about excavation speed, but there's one upgrade that's supposed to increase what's dug up, and I'm convinced that doesn't work as intended. I've had the upgrade applied before and have literally received only two one-star fossils.

The yield upgrade only applies to the “extras” you can dig up. Like minerals and such. I’m fairly certain the description states that.

Like you said, it certainly doesn’t increase amount of useable fossils

Yes, the performance upgrade only affects minerals, not fossils.

Well, I've been testing the speed of fossil extraction and it really works but not as fast as it should. The problem is that without any improvement the extraction of amber fossils is very slow, about 45 seconds. With an improvement of 120% I should go to about 22 seconds and my game says it takes about 30 seconds.

The excavation speed improvement does not work. An expedition to Hell Creek always lasts 2 minutes.

Having three expedition teams with such a slow extraction of fossils despite making improvements is a waste. The fossils accumulate all the time without having space and it compensates more to have the space improvement than the speed one.

Then it definitely doesn't work; the example I used (two one-star fossils) was literally all I got from the dig in question. I didn't get a single mineral from it!

It works. I've applied two to my Research Centers and I get 2+ per team I send out.

It's still rng based as to whether or not you get more things to sell, the upgrade just gives you a better chance.

Yes, the excavation performance works, only it is based on probabilities. What does not work is the speed of excavation. With 150% speed going to Hell Creek and back should take less than a minute and it is not.

I get plenty of extras in my game. I use the 10% yield upgrade.
