Treatment period in graphs #10

Hi, I'm using synth_runner (version 1.4.0) on Stata/MP 13.1 for Mac (64-bit Intel). When I use the trends option, the treatment line gets shifted to the year prior than I specified. Is that to be expected?

I don't seem to have this issue. When I run the below with and without the trends option, the graphs have the exact same treatment

synth_runner cigsale beer(1984(1)1988) lnincome(1972(1)1988) retprice age15to24 cigsale(1987) cigsale(1980) cigsale(1975), trunit(3) trperiod(1989) gen_vars

Possibly this was inadvertently fixed in newer releases, so I'd try that. Also note that you can use the trlinediff option to the graphing commands to set the horizontal offset of the line manually.
