Vision 2 upgrade is unlocked in shop (cannot be purchased again) no new planets to explore.

I've read the dev posting a couple years ago about updating the achievement to make it less grindy, but this is still at a ridiculous state. I've played the game for 18 hours and have 100% maxed out everything possible. There should be no reason you need to utilize an autoclicker overnight in order to get the last achievement. Worst case scenario the dev could've just made an end-game planet with 10 million blocks on it to break, but no; we're instead left with restarting a trillion times on the blackhole ...

I've been trying to 100% this game for the past couple days and I've gotten most of the way there, but suddenly my destroyed block counter got stuck at 16.777 million? Usually the way i grind it takes ~1 hour to destroy a million blocks, I've been doing this for 30 minutes and the counter hasn't gone up one bit. Is this just some bug?...

I find it strange how going from Home 1 to Home 2 makes me take less damage than increasing the Block HP by 15% for the challenge on Home 1. Considering Home 2 says "8X to Gems, ore, and block health" it feels *VERY* off and i can't help but wonder how its calculated....

Wondering if i am missing out on some upgrade somewhere. I have been farming moon coal, prestige 1 aluminum and prestige 2 iron, silicon for hours. I was expecting some progression by now but i still barely can scratch sulfur or prestige 2 aluminium without exploding. Is the progression meant to be this slow?...
