That's strange, the error is specific for a blank (undefined) swtich or switch ID equal or less than 0 and from your screenshot it's not like that
I created a check with the same configuration but didn't get any error π€
Okay, I've turned off all of my plugins except for WD Core and WD Stats and Skills; the new error message reads;
this.checkFormulaEvaluator is not a function. Does this help you at all?
Also, I managed to re-create the error in a blank project! I uploaded it to my Google drive for you to test out; do you have a way I could send you the link? :)
It's okay, haha! Sure thing, here you go! https://drive.google.com/file/d/1ZF5ZemzS0myOFvEcBo_Mx7WQ9XvntOJH/view?usp=drive...
Oh, okay! So it's something I'm overlooking. I found the Skill 7 stat and changed it to Skill 1, but I still get the error? WD_StatsAndSkills: Can't find a valid Skill ID for manual buff command! Skill1. (I changed the Other Events Phase Change number/formula box; It was set to Skill 7 but I made it Skill1. Is there another place I should look for it?)
Here is a re-upload featuring the error, but with the Skill7 thing fixed; https://drive.google.com/file/d/1Bso-3LCA2DE1INPyNM-GBjMYMDCUZ1zl/view?usp=shari...
