Is there any obvious reason why Piston would not apply changes when updating plugins? It seems to go through all the motions when I run "piston update vendor/plugins/my_plugin" but never seems to make any changes - the last line always readys "Updated to r123 (0 changes)" regardless of any changes in the repository.
I've tried re-importing into Piston, but it doesn't seem to make a difference. Any suggestions?
I'm using Piston 1.3.3 and Ruby 1.8.5 on WinXP
