PoE issue on WS-C3750G-48PS after removing member switch from stack

Hi all, I'm having some weird power issues with PoE after removing a member switch from a switch stack. I made sure the stacking cables were tight, unplugged all four switches, brought them up one by one, and the master switch (the top/first switch) is giving me the blinking amber PoE light It's funny because most of the devices in the switch are receiving power, but there's just a few that will not pull power. Also, this was happening on switch two last week and I ended up just replacing the switch with a spare and it seems ok now, but now it's happening on switch one. I can't imaging that two switches would 'die' at the same time after removing one switch. Here's the logs for "debug ilpower port" and "debug ilpower powerman":

The "ILPOWER-3-CONTROLLER_PORT_ERR" only show up for switch one. All three other switches work normally. If I remove a PoE device from switch one and plug it into any of the other switches, it works fine.
