### Summary

When performing a memory calculation, it starts at 0% and reaches 100% after 3-4 hours. Before that, memory calculation worked in 5 minutes. The character no longer flies during memory calculation, but simply stands still.

I’ve been trying to solve this problem for over a month now, but without success. This problem makes it difficult for me to publish maps and make new updates.
