UPDATE: This appears to have been fixed as of 10/22/2018. This should unlock normally now without the previous workaround. Simply building lightning tower and letting 100 lightning strikes occur cumulatively over multiple maps will unlock this. I am leaving up my previous solution for a little bit longer just incase any issues emerge in the coming days, but all reports are that this has been resolved. Thanks everyone for your feedback, updates and reaching out to the developer to fix this! 
I'm making this solution because I've now gotten multiple requests from other TA'ers who have had this achievement glitch on them. Based off the fact that only myself and a few others have unlocked this past a certain date, it would appear that a recent patch for Aven Colony has made this achievement unobtainable. I used the below steps to get this to unlock, and one other TA'er so far has used the same steps for them, I can't promise it will work but it has for me.
You will need a
Disk version of this game in order to do this.
You should also unlock every other achievement before trying this (you probably know what is coming.)
Step1: Completely delete all save data for Aven Colony on both your Xbox, and the cloud (permanent wipe, thats why I said unlock everything else first.)
Step2: Uninstall your game
Step3: Put your Xbox on OFFLINE mode.
Step4: Reinstall the game from the disc, with no online updates (thats why your xbox is offline)
Step5: Start the game, play either of the first 2 story missions (i preferred the 2nd mission). The missions are incredibly easy,and you're not really at risk of losing. So I just built some farms, built some mines/nano producers. And then built like 20 Lightning towers spread across the map. Let the game play out for a while at this point, feel free to count or to just guess when you've reached 100.
Step6: Go back to your network settings and reconnect to the internet, but
DO NOT let the game update itself.
Step7: Now you should be able to recheck your progress (you cant check in offline mode).
Step8: At this point, if you were short of 100 lightning strikes, your progress tracker should have advanced pretty close. If you are short (remember dont update the game) just turn off your internet, and start grinding again. If your tracker is showing 100%, then I think it will unlock right there, or you might have to start the game updating. But at one of these points it unlocked for me. It might take 5 minutes.
Hopefully this helps everyone that has had this glitch on them. I sent the developers an email which they responded to very quickly, and I explained to them the issue, and they said they would log it. I would recommend other people if they feel so inclined to shoot them a support ticket too, so they feel more pressure to fix it.
