bruh why you receive this error cause they have method to use here example (Method_1, and etc.) cause they are "static encounter" you should aware that and it will defend on the nature you want like example you want Adamant nature with 6IV that was impossible to have you should give up -1 value on whatever IV you want to have secure the correction of PID you can use (PokeFinder 4.0.1) to get correct PID, SID and etc.
