Repeat: Bad alignment request

Hmm. Just had an old build script that I use to set the filetypes of things to be distributed (when they aren’t being kept with filetypes in SVN) stop working quite badly when I removed one now-redundant directory that it referenced. Simple example, with a Temp directory that exists in the root:

Repeat Echo $.Temp
... shows contents of Temp directory ...

Repeat Echo $.Tempe
Repeat: Directory '$.Temp' not found
... that's fair enough ...

Repeat Echo $.Temp
Repeat: Bad alignment request
... and so on until the end of script when good objects are being referred to ...

It seems to clear on a Task swap. I dare not ask.
