Streaming PLAYBACK file through LSL

in OpenBCI_GUI
Hi, has anyone encountered an issue streaming a playback file through LSL? The GUI is loading the .txt file and playing it on screen, however when I try to network it through LSL (time-series on stream1), the stream shows up on LabRecorder, but the stream is empty (not passing any data)...
Comments
A side-note: This happens only on PLAYBACK data. Streaming real-time, or synthetic works fine.
@harelasaf Please make sure you are using current version == v5.0.3.
If you are already using this version. Can you please make this an issue on Github?
Thanks! Will take a look at this.
