If you dont know how to editing the script by yourself, here is a small description:
go to this: https://pastebin.com/sCjjzFSg
and copy all raw data
then go into TTS and load the save
click on scripting
then you should get a window with all scripts
look for "Scripts - 75ab50" on the left and click on it
click in the script and press CTRL+A and DEL
now paste your copied text from before with CTRL+V
lastly press the "Save & Play" button at tthe top left


If you know how to change scripts in TTS here is the line to change:
Line 456:
Wait.condition(function() figure.call("setTyp", {params.monsterDifficulty}) isSpawning = false end, function() return checkLoaded(figure) end)

This line should be changed to this line:

Wait.condition(function() Wait.frames(function() figure.call("setTyp", {params.monsterDifficulty}) isSpawning = false end, 1) end, function() return checkLoaded(figure) end)
