re-patching bug

RH4. v2.0.0 b.509

Show is already patched, all is working correctly.

Six fixtures have been hung in reverse order today, so i try to reverse the patch. Originally 107 through 112 are at 001, so i type 112>107@001, then confirm removing the existing fixtures.
Now the even numbered fixtures are correct, but the odd numbered fixtures are unresponsive and in their "unpatched and pointing at the ceiling" position.
Log off show, log in again and they realise that they are patched and all is normal.
I've repeated this with different fixtures, same issue.
