Points, my Inventor discover above 10.000 are transfered to next invention?
only 10.000 invention points will be deducted... and if inventor is working, it will stop and you will need to send him again.
Hmmm... Lets see:
I have 9.999 points. I send my Inventor to work. After ~2min. Invention is done. Inventor is free and I have to send him to work again... spending NEXT 3000 satoshi i 200 exp?

If you sending him to work, the invention will not be finished in 2 mins.. Maybe from event, but it's random.. and you still can wait to finish inventor work and save 3000+200.
But it will happen VERY rarely, believe me, maybe never
I'm scare I still don't understand.
version 1.Points are counted (but not displayed) every refresh. In this version I understand phrase:
"only 10.000 invention points will be deducted... and if inventor is working, it will stop and you will need to send him again." and then I'm asking for lost payment. I've pay 3k and Investor don't work after current Invention is finished.
version 2.Points are counted once, after 24h work. That means: when I start with 9.999 points Investor end with (f.E.) 10.782. 10.000 is deducted for Invention, and what's with 782? And in this option I don't understand
"it will stop and you will need to send him again"point 2) is correct.. it'j just counting once / 24h and he will stop, however with very very big probability he will not work at this time
