No, it screwed up all my 1x screens, i just updated to sketch50, then i do my craft sync as usual, then i login to invision to check.........then all my screens are half size down!!!! Then i found out the reason is, no matter what my settings were on sketch, when i click craft sync, it always changed my file name to @2x and uploaded into invision! i tried to renamed them to @1x, not working, and then it broke all my interactions on craft sync! T_T Not sure who can fix this....
