Building the Tamiya Gloster Meteor 1/48, I had some problems with decals as well.
Strangely almost all the decals went on perfect. The fluently adapted the with some set and sol to alle curves and panellines.
Two decals - the large roundels on the wings - all crumbled up. The two large decals that were ;layed on a perfectly flat service, went wrong. I was very surprised. I used a nother set of roundels to fix this. This didn't work out brilliantly as well, but luckily was less rinkled.
