[Therion] 2 fixes for a point with standard deviation

[Bruce Mutton]

I have done this in the past I am pretty sure, but a very quick look just now makes me wonder if I have resolved all the multiple fixes in currently active projects to single fixes.  Sorry, not much help.

Therion really doesn't seem to like using Survex for fixed points :(

When you have exactly 2 fixes for a station, Therion 5.5.1 (with Survex
1.2.42) gives up when processing survey data, and gives no reason why.

There is a workaround; specify every fix twice. The result will be the same, but it will actually work.

I get the feeling I am "holding it wrong". Surely this must have been a problem for someone in the past. Bruce, how come this has not broken your surveys?
