Likely too much lube or if it was in a solder only board the solder could've cracked , ive had it happen before

Haven't had the same issues with 67g tangerines. Mine are l&f with 205g0 and deskeys films and been using them for more than a year.

I did I have some issues with them though. When I first ordered them, a few of them were defective due to the bottom housing. I swapped parts on the switches until I narrowed it down to the bottom housing was causing the problem. Ended not being able to resolve the issue and use the switches for part spare parts now.

The other issue I had on the was spring ping. Before and after l&f I had a bunch of switches that were extremely pingy. I fixed those by adjusting the film and adding more 205g0 and some of the ping went away over time. Currently, there is no ping in the switches now. However, I have a few switches that are still extremely pingy and I couldn't fix. I just don't use them.

I've used Tangerines in a few boards, and never had this issue. I've never read anything about this from others either, so I doubt it's an inherent issue with the switch. It doesn't mean it's not a faulty batch though. I wish I could be of more help, but mine seem fine.
