The map does not contain a slope data sector. This sector is required by the slope mode to store data for the slope vertex groups.

You have two options:
<ul>
<li>Use selected sector: uses the currently selected sector to store the slope data. <span style='color:red'>Make sure that this sector is only
used for this purpose! Do not edit or delete it!</span></li>
<li>Create sector in CSA: automatically creates a new sector in the control sector area. <span style='color:red'>Do not edit or delete it!</span></li>
</ul>

<b>Creating the sector in the CSA is the recommended method to use.</b>", this.BackColor.R, this.BackColor.G, this.BackColor.B, this.Font.Name);
