Describe your environment:

• VuhDo v3.136-tbcc
• WoW US/Oceanic Server
• enUS client language

Summary of the issue:

Just created a new layout that includes the following:

• Panel 1
  • Groups 1-8
  • Special group, pets
• Panel 2
  • Special group, self
• Panel 3 (with "Target" extra panels enabled)
  • Special group, target
  • Special group, focus

Now, upon logging in with no groups (solo), Lua errors crop up from VuhDo, according to BugSack.

Expected behaviour:

There should be no Lua errors.

Actual behaviour:

The following errors were captured by BugSack:

Seems like sometimes, a panel's :GetTop(), :GetBottom() methods may return nil.
