<p>Hello,</p>
<p>Thank you for your response.</p>
<p>Unfortunately, I am unable to test previous versions (0.14.3 to 0.14.9) due to a change in EPSG support: the EPSG.io API endpoints, which we rely on for the EPSG:2039 projection, </p><p>was deprecated on 01/02/25. As a result, these endpoints are no longer functional for me.</p>
<p>Given this limitation, is there an alternative way to troubleshoot this issue?</p><p>Would sharing my LAYOUT configuration help in diagnosing the issue?<br></p>
<p>I appreciate your help and any guidance you can provide.</p>
<p>Thank you in advance!</p>
<p>Best regards,<br>
Nimrod Cnaan</p>
