Severity *

Low (Minor/Nuisance): Minor glitches or cosmetic issues that don’t affect gameplay and occur rarely.

Brief Description *

Trying to export a Warship Record Sheet to PDF results in a null point exception and if you attempt to print any warship record sheet after the fact it results in a a null point exception and gives you a corrupted PDF file that is unable to be opened necessitating Mega Mek Lab to be reopened to print a sheet succesfully.

Attempting to print without exporting prior results in the normal function of the process.

Can you post the log file? I think this might be the issue that was addressed in #1601 .

Edit: To clarify, we need the logs from when you try to export a warship PDF.

Totally missed and forgot about that prior issue, I did notice it last month when browsing but didn't remember/notice it again when I posted this issue.

Printing the Enterprise Super Carrier results in this exception (but a functional PDF), possibly because the RS is two-sided. One-sided WS like the Nightwing causes no errors.
