Hello! Awesome scripts!I found that under the A* weight script, there was A memory leak because the path was drawn in real time and A* script was called A lot. However, I could never find the cause of the memory leak.

I have just uploaded version 1.1 of the scripts and reference project! To my knowledge, all the memory leak bugs have been fixed. In a test project, I called all three algorithms every step for 5 minutes straight and saw no increase in memory usage. So hopefully this will solve your problem.
I apologize for any delay this might have caused in your development. As always, if you have any more issues with the scripts, you can post again here or message me on Twitter.
