* Fix roundstart seed and fish asset runtimes (#71452)
## About The Pull Request
Fixes annoying roundstart runtimes coming from a wrong deduplication
method. `sprites[id]` was empty at the time of the check and only got
filled when it started actually building the spritesheet. Now it's
tracked in a local variable.
No changelog update since it's not visible on the player side.
