Okay, last idea; Let us buy these bugs? (at a price that's double what they're worth on a 1.5x day, so absolutely no profit can be made).

Throw in an NPC somewhere in the railroad caves that sells the bugs that no longer spawn due to these issues. It can just be temporary. Even if he's just there for a month. Just to give people who want these bugs for house decor-purposes a chance to buy them if they so choose, given the fact that they were abruptly removed because of spawning issues.

I know I'm not the only one who would really appreciate this.
