Group persists after edges should have decayed #31

I'm running TILES (non-explicit version) using data ranging from 1992-2018. The input file is correctly formatted, with two columns of node ID's followed by UNIX timestamps (seconds truncated). I want the edges to persist for only 365 days, and I want snapshots of the groups every 365 days. Right now I'm using the following in the command line:

python tiles filename.tsv -o 365 -p output -t 365

Most of the groups appear to behave normally, with the edges disappearing after 365 days, but for some reason three nodes that only have edges in 1992 and 1993 persist as a group until 2018.

Do you have any ideas what the issue might be? Are there any other assumptions that TILES makes that aren't included in the documentation?
