Still seems to be the glitch where if you ask ignition to show you a tag before it knows about it, you have to disable and re-enabled the PLC topic to get it to show up. Previously, it would show up as a folder when browsing via the OPC.

I just did a test to confirm. I added new tags to 4 PLCs. On two I told ignition to rebrowse the PLC before adding the tag to the ignition database and two I told it after I added the tags. On the two I told after, the tags show up as null. The other two got values just fine.
