Building Count Fluctuations

During expansion of my current base, I'm seeing wild fluctuations in build count (max 1,500), particularly when adding a ceiling light fixture. I was pretty close to the max (1498 I think) when originally trying to add a ceiling light (specifically the Lantern Pendant Chandelier) and it bumped me to 1536, not allowing me to place the ceiling light or make any changes to walls. I then heavily pulled back on building pieces to get well below the limit (1441), then placed another Lantern Pendant Chandelier, and my building count went up by 50 (to 1491). Am I infact at 1491 and the light is just correcting the limit, or am I actually at 1441 (or even lower given how much I tore down) and the light is causing an artificial jump in building count? I thought about trying to manually count build pieces but ick. Hopefully you can reproduce this and find a fix? I'm actually surprised to not find someone else sharing the same issue.

Note: wall lights do not incur this issue, and I haven't tried different types of ceiling lights (out of fear I'll be bumped over the limit again).

Edit: Sorry, I am now just seeing another post about the same issue. Feel free to combine.
