Speaking of exploits, I found one. Energy crystals can be crafted from rubies.
That doesn't feel like an exploit; Rubies can only really be used for a few things, and those few things they are used for are even more valuable than diamonds. And I have yet to have a game where I found more rubies than diamonds, which shows that Rubies are actually MORE valuable than diamonds, through virtue of their high-tier tech usage and their overall rarity. If anything, this lets you trade 1 item of a more valuable resource in exchange for 1 item with greater general versatility. It's not getting higher amounts of something, unless you were literally crafting ALL of your diamonds into Energy Crystals.

Tbh, immibis, I haven't seen anything from you in the last 3 weeks that has really advanced the conversation; all you've been posting is 'exact words' nags to greg about what you want what he's saying to mean, and completely ignoring what he's actually trying to say to the rest of us. (To some, it could easily be classified as trolling.) And, once again tbh, it's kinda getting mildly f*cking annoying by now. It's not the first time I've seen someone do this, and seeing it again doesn't get me any less pissed off at it.
