navigating change of remote work location on stem-opt while awaiting h1b lottery


I’m on F-1 STEM OPT working remotely from Dallas, Texas.
for a Company C located in state Y.

Company filed H1-B with location Dallas and location Y as two possible work locations.

Now my lease in Dallas Texas is over and I want to relocate to state Z because of personal reasons.

Will this change of address have any impact on the pending H1-B petition ? I was not able to find much information regarding this.

Please help.
Company is a start up and don’t have much idea about immigration, and the lawyer they hired is making them dance as he wants.

(I’m of the opinion that the STEM-OPT and H1-B are two different things, so I should be able to do whatever I want until October 1st, 2018. The H1-B work locations would be valid only starting OCtober 2018 (if h1b is picked))

kindly point me to any resources.
