Update your tiramisu install by downloading and replacing the files from tiramisu.foryour.cafe, delete the installed dlc with NUSspli (important as NUSspli will delete the bad ticket too) and try installing it again
@K3Nv2 I got some cheapies at wallys, that are pretty good, already have lost a few expensive ones (one falls out and gone, can't find) while cutting grass so bought some cheap ones, and of course never lose these cheap ones. (Cheap meaning only $35, compared to air buds which I only have 1 of 2 now)
