Increased Trade Window Size crashes game when playing online

In singleplayer and multiplayer TCPIP i am able to completely fill the oversized trade window i created as seen filled with items here:

keep in mind the patch is duplicated and running on my server machine and my client

It does not seem to crash the game whatsoever over multiple tests, but when playing on bnet though on a pvpgn server running 1.13c as soon as i put an item into a slot in the last column on the left the game crashes. Still debugging but wondering if someone can save me some time. As it seemed to work just fine and had for months until i got the server running and started testing. everything else seems the way it does in any game mode weather it be offline or online. but this one issue not being able to completely fill my oversized trade window has me stumped

Solved: dimensions were not perfectly calculated as i am making this window custom and no one has ever done it before to my knowledge. The width across the window has to take into account the space in between in columns and rows and well as the outside's  just a bit tricky to calculate. case anyone is ever trying anything similar
