Resizing Tag Block in Halo 4 campaign can break gameplay

[JoshTheGameDev]

Adding a Target Tracking type on the Rocket Launcher and any other weapon in mission m40 (Reclaimer) will break the Target Locator and cause the mission to be unplayable.

Issue extends to adding to a Tag Block of any type.

Possibly affecting the script or trigger used for it.

It doesn't do that for me, How big of a block are you resizing? and what Version of Halo 4 are you editing?

[JoshTheGameDev]

The latest PC MCC version - Steam. (Build ID 7043710) And the latest build of Assembly (2021.07.22.14.03.25-dev) I've managed to repeat this using a backup of the map I made before editing too.

From a clean m40_invasion.map file, all I do is:

• Go to storm_rocket_launcher.weap
• Target Tracking
• Under "Tracking Types" add 1 new element (from 0x4 total size to 0x8)
• Call it "ground_vehicles"
• Save
• Play from start of m40 (Reclaimer)
• Go up to the part where you have to obtain the Target Locater
• Try using the Target Locator on the Phantom objective

It will just not allow you to use the item

It has the same problem when trying to add a single element under Tracking Types for any other weapon too.

Making any other changes seem to work fine, it's just isolated to adding/resizing a block

Hazarding a guess that this isn't an Assembly issue, but rather an issue with the engine itself.

@0xdeafcafe Gonna have to agree with you on this.

Apologies for neglecting issues but this is due to the tracking types block being shared across multiple weapons. When adding elements old data is 0'd out to free it for use elsewhere which will break any other instances. Its probably way to late now but the solution would be to select "isolate shared block" underneath "add or remove elements" in the block gear menu.
