Vaal Temple Bug or something

Hi, I'm looking for an explanation about this issue, which I couldn't find in the bug report forums.

I built the temple on a long chain. I understand the in-game temple logic, but why did my temple get deleted like this? The room in the middle of the chain got deleted randomly. I built the temple in ONE WEEK.YES, ONE FREAKING WEEK WITHOUT DOING HOLTEN EXPLOIT. I'm done with this game. This ruined my experience for the entire league.
