Bug with fleets doing items. (UM5.)

[Paul1231]

Things like, scrapping ships. Terraforming. Gives me an instant CTD. Those are the only things that I tried, before I uninstalled it. This is my first time trying that particular one. I usually prefer the Planet Mod.

not sure if same issue but terrform issue was reported here
viewtopic.php?p=59107#p59107

it is possible scrap issue might be related?

EDIT; I can confirm scrap issue windows "event viewer" gives offset of 0046a001
this happens with multiple ships scarped in same task force.

Is this also related to the larger task force patch?

Sub 469FB0 CheckEndMovement is part of ProcessMoveOrders:

Code: Select all

0046A000           mov   ax, [ecx+34h]  // race ID from task force

OT @ larger task force patch: How does this even work for AI system attacks when AI is not allowed to use more than one ship/TT per fleet?

there does not seem to be a loop over the attacking task forces (if more than one task force attacks). It seems that they are processed one by one.

I saw that also, but this is new and only happening on UM5

Galaxy, UDM and UCW is only other mods with taskforce patch and none has these issues and AI will still assault systems with single ship task force.

UDM and UCW does not have all the new patches UM5 has (not sure about Galaxy mod), So I expect it is a patch conflict just not sure what patch is culprit.

this is new and only happening on UM5

New means UM5.5 only? I never touched/examined the UM5.5 ship scrap codes or any other industry to credits conversion features.

Restoring vanilla ship scrap subroutine (+ re-adding task force patch) is my only idea for this conflict, but only if issue is not new i.e. also present in older UM5.X versions.


However, I did not consider the task force patch when collecting my patch suggestions for UM 5.5, so better check whether the task force patch shows a conflict i.e. an improper implementation.

AI will still assault systems with single ship task force.

So in low tech games, using TT version 1 against bigger systems, AI should fail very often due to bad success chance and/or lose many TTs even by success?

task force patch show no conflicts, So I expect it is some type of calculation error happening here due to taskforce patch.

in UM5 you can scrap 1 ship at a time without crashing, but 2 or more will cause CTD

also just tested scrap crash when 18 FT patch is removed no crash "Task force 9 -> 18 in UM5 patch folder"

This code should conflict with the task force patch unless QD created a special exception variant:

Code: Select all

46942A     83C3 04            ADD EBX, 4  // -> 2 @ 0x6882C

EDIT: More possible instances for the same conflict:

in quick test these 2 fix both issue (terraform and scrap)

Here are updated patches (displays red on UM5 as expected) just install using QD patcher

Glad to hear the fixes work, but we need to memorize that adding/removing the task force patch gets very messy depending on other patches used...

I did create new patches for UM5 patch folder (available next update)
Instant-Terraforming Bug (fix) UPDATE 18 TF fix
Ship scrapping Disable the exploit [square root] (fix) 18 TF fix

these are full patches that could be used if 18 fleet task force is already applied
