I have a so far irreproducible error where some transaction group that I have active errors out with a complaint that the t_stamp field is missing. I am confused, because this should be a totally internally managed field. I have "Store timestamp to: t_stamp" checked in the transaction group. I am running 8.1.31. The only solution so far is to stop the transaction group, save, start it, and save. It then works for some time before it breaks again.
Does this ring any bells for anyone? I want to open a support request but I do not yet have reproduction steps available.
