Quest ID 9531 broken [Tree's Company]

[IvanLlanas]

Description:

Quest 9531 [Tree's Company] cannot be completed.

Current behaviour:

After disguised as a tree nothing happens. [Engineer "Spark" Overgrind] should have appeared and talked to [Geezel].
[Geezel] appears to the very south but he stays there until the disguise effect fades off and Geezel despawns (it can be killed by another player).

Expected behaviour:

[Geezel] meets Engineer "Spark" Overgrind]. They talk a bit and the quest is completed.

Steps to reproduce the problem:

1. Get to the flag and use the disguise item.
