I have never owned a tote bag with the clear plastic top and because of your post I will never purchase one.  Sorry for your bad luck, but thanks for letting us know.

I also wouldn't place the fault on the tote.

 I've had no issue with leaving balls in a tote bag. I try to not let balls sit for more than a month. If I don't have a tournament in the near future I'll at least take the ones that have been sitting if I go to practice

If I had to guess I would say the issue is more no rotation than the temperature change inside your bedroom.   Either a coincidence only cracked in see through or perhaps balls you stored in it more prone to cracking or it could be a matter of less insulation not to temperature but to the weight of the balls.  I store my urethane and plastic in see through totes in my garage (totes not on concrete directly) where it often gets over 100 degrees (but never cold) for over a year now with no issues but religious about rotating the balls twice a month as well as throwing all of them occasionally.

Whereas I don't rotate any of my balls, and i Have yet to have one crack.

Due to an ongoing injury, I haven't bowled or touched a ball in 18 months.
I have 3 balls in my office sitting on ball cups. None rotated, not one has cracked.
I have 4 more balls sitting in a Storm 4 ball Rolling Thunder carrier; both compartments are open to the air, haven't rotated one ball. None of the 4 cracked.

In my basement, Humidity varies from 50% to 70%; temp varies from 58 degrees to 69 degrees.
I have 6 balls sitting on a carpet, on a cement floor in the basement. None rotated; not one has cracked.

I also have 8 more balls, sitting on ball cups on wooden shelves in the same basement; haven't rotated one of them. None has cracked.

I strongly suspect rotating balls has nothing to do with balls cracking.

I have all my balls(except the 4 in the league bag) on wood racks in my bowling ball work room(formerly my utility closet).  Just recently I was aware that I was late/behind in flushing out my ac drain line in my 8th floor condo..unfortunately I didn't realize it until I woke up one morning...no time to flush it out..had to rush out to work that day and because the drip pan was already backed up and overflowing/dripping through my ceiling, I had to turn off my ac while I went to work----now this is south florida in mid july...and a few days later I found that my Visionary Crimson executioner and my Track Flare had cracked.  The other 18 or so balls on the racks were fine.

Could just be those balls because the first crimson execu8tioner I had I bought used and it ended up cracking at some point, and also the first Track flare I bought used  about 9 yrs ago ended up cracking at some point.  The good thing is my other Track flare was in my single ball bag at the time, so no harm done there.

One thing I have going for me is I only have inserts in a fairly small minority of my balls.  Seems like inserts increase the odds of getting a crack started especially if done shoddy.

That I would have to agree with. Some drillers can get careless with beveling and glue placement and amount.
Thankfully, mine was fairly conscientious about them. I tried to follow suit.
