Local map and other menus become blank in some locations while playing Wizards' Islands mod.

As the title describes, the local map disappears in some cells and only the cursor showing the player's location remains. The same happens with the mini-map. However, the world map is not affected. In addition, the character sheet also becomes blank sometimes and the icons in the lower left corner as well as the active spell effects adjacent to the mini-map become empty. The name of the equipped weapon above the inventory menu and the name of the selected spell or enchanted item both also disappear sometimes. In an affected location/cell, the local map is generated but cannot be seen. This empty local map can be seen if the cell in which this issue arises is right next to a cell in which the local map works fine. Another issue with the menus is that when there is no local map, the name of the equipped weapon does not change after changing the weapon either manually or by using a hotkey. None of these problems were seen in vanilla Morrowind (GoTY edition) and were observed on Windows 10 using the 0.47 revision ab28847e.
