I've observed wheezeworts being uprooted and their seeds destroyed if the game was saved/loaded when they were in a stifled state. In my case it was because I spawned in 400kg of ridiculously cooled hydrogen, however for regular cooling setups, i.e. co2/chlorine solidifiers - they often temporarily stifle.
I've noticed it in normal and debug games. Can be replicated on load. Please find attached save and short vid.
As mentioned, if this is intended behaviour, kindly delete the thread.
Steps to Reproduce
Stifle a wheezewort, then save and load.
