BUG: Assembly Engineer Fortress Knockback

[Verathian]

• I have checked that this issue has not already been reported.

• I have validated that this issue is not a syntax error of either MySQL or SQLite.

• I have pulled the latest version of the main branch of DarkflameServer and have confirmed that the issue exists there.

Issue Description

On occasion when fighting dragons in Forbidden Valley, the personal fortress does not prevent knockbacks, but the player is locked in place and can't move during the duration. This causes you to occasionally be knocked off edges.

Reproduction steps

In Forbidden Valley Dragon Battle (where this is most common), use the fortress ability and knockbacks will occasionally knock you out of the fortress.

Expected Behavior

The fortress should be preventing all knockbacks from all sources.

Environment

Client: Windows 10 + Unpacked Client (unaltered outside of the steps provided by DLU).
Server: Ubuntu 20.04 running the recent DLU update with the corrected chat filter.

If I recall correctly this was an issue in Live as well, from time to time.

Can confirm this is also an issue with the dragons on Crux Prime.
It's not a full knockback though. The player is pushed backward, but not completely out of the fortress.

This is partially, if not fully addressed on main. Please pull and verify if the issue exists on latest

I am having the same issue. It applies to all attacks that deal knockback, such as the admiral's cannon, the ape smash attack, and the dragon attacks. The full knockback effect is applied, leaving the player completely outside of the fortress and can lead to death if knocked off a ledge. It does not always happen, but it is frequent. I am running the latest version of the server on Windows 11, following the native windows setup.
