New lot trait triggers endless notifications

I added the new event lot trait to a lot worth over 500k. For maybe half a sim day all was fine, and then I started getting 'Lot below 250k' 'Lot above 250k' notifications on the loop. They only stopped after removing the trait. After each notif, my sim started a little celebration animation too, so aside from visual mess, it also looped me into an inifite animation (bc moodlets kept switching).

PC, no mods, R&L installed. Sims affected are nobles living in a renovates Thebe castle in Verdemar (in case it's the lot glitching).

The lot value never went below 250k. I was also not doing anything that could change lot value at the time (my sim was teaching their toddler some blocks).
