Man you go through a lot to make sure it doesn't crash. Haha. Mine sits in a cardboard box in the closet, top not even closed. I use a lot of jugs too (20 ml and 50 ml), so some of my gear has been in there a long time. Been doing it that way for 22 years and never had an issue.
As far as crashing, no. You would either see crystals or a film-like solution on the bottom. Like Jipped said, the oil could have oxidized. The only way I would think it would go bad, is if it wasn't actually sterile or there was not enough BA/BB in it.
Mine are in a one of those cheaper, keyed lock boxes & I have some little foam things for vials that I put them in.
Except mine are only 3 holes mostly & I have two foam holders that hold 6. vials I also have some plastic vial holders, but they're too small for most vials unfortunately. Although I have a plastic one in my fridge for peptides.
