BUG - server logs spams by SourceId NOT found

Kind of took things to the limit.

~480ish treasure tokens, 8 [[Roaming Throne]]s, and [[Reflections of Litjara]] on a Miirym deck. I decided I wanted to swing out and see how much damage I could do after stealing [[Nettlecyst]] and [[Adaptive Omnitool]] from an opponent. Put Nettle on one Roaming Throne to protect it, and cast [[Blastphemous Act]] to clear my board so I could cast and copy [[Twinflame Hellkite]] without [[Ganax, Astral Hunter]] trying to make 100 instances of treasure on the stack.

However, I forgot I had three [[Wrathful Red Dragon]]s on the battlefield. Act goes off, everything dies, and my client immediately disconnects. Server is still running. I can connect back into the game, but it immediately disconnects again.

I check the logfile and I have.. 79MB of.. (Trimmed from 303,000 lines to... This.)

Despite me never playing the card over the course of the game. The card is in my deck, but was not on the field.

This tells me something somewhere was wrong even at the start of the game and the server was spamming errors the whole time.

Start at the MageObjectReference. entry point named in the server logs and trace how sourceId and LKI lookups behave after cards leave play. Reproduce the reported Blasphemous Act and Dragon-trigger scenario, then verify that the server remains usable without repeated SourceId errors or client disconnects.
