Bug Report

crash-2026-03-11_15.01.06-client.txt
When clicking on a scroll from Custom NPC+ in my inventory, the game crashes with a NullPointerException. The crash happens because NEI (the GTNH fork) fails to calculate the item panel bounds when the kamkeel.npcdbc.client.gui.inventory.GuiDBC screen is active.
