Most of my projects had been put on a back burner so I could complete the file transfers and the Index of Mods. It was an arduous, energy-sapping task, so I needed a long vacation.

Yes, I'd like to finish what I started.

I've downloaded it from github. Windows Defender finds Trojan:Win32/Pomal!rfn    Release v251 also has Trojan:Win32/Suschil!rfn

That's a false positive.

There is newer version v252.01-nightly-fc5a92f without any trojan. Can I use it?

There are some known issues with newer versions. Please use v249 for now.

Should I install newer version of WeiDU after I extract BiG-World packs to game folder?

Get the amd64 version and extract weidu.exe into your BG2 directory. Then, rename weidu.exe to setup-weidu.exe so it can later auto-update other WeiDU installers. Next, run the BWP installer. Finally, biff the files with Generalized Biffing (if BWP doesn't do it for you).

I'm not sure, but BWP may also try to launch mod setup with auto-updates disabled. In any case, the question marks in WeiDU log often mean an outdated WeiDU installer was used at some point. So check if this time the BGT folder is in your BG2 directory. BGT should also be correctly shown in the WeiDU log, without the question marks.

Should I make complete re-install of the game with mods from scratch now? Will save file work?

I'd do that. Your current saves should work.

According to Area CRE Checker in my ar8900.bcs there are several Viconias.

That's because a different variant is supposed to spawn based on your character's level.

When trying to enter Peldvale (AR8900) I get error message: An Assertion failed in ObjCreature.cpp at line number 12349.

This kind of an error indicates problems with loading a creature file. This particular one is probably caused by an invalid spell file reference (described and solved here).

Installers like BWP have been outdated for several years. There may be other issues later on.

BGT/BGT.TP2~ #0 #0 // ?????? -> : ???

This could be a problem, e.g. an incompatible WeiDU version, during the installation. Make sure you use WeiDU v249 for all mods. You should also biff the files at the end for better performance.

Please attach your WeiDU log.
 

And there is really no folder called BGT in my install. Though I do have BGT installed with BiG World Project.

From your other post, if the BGT folder isn't in the BG2 directory, something has probably gone wrong.

See this issue related to WeiDU v251. BGT creates BIFF archives and should be installed with v249. I checked the Linux version some time ago, and it should work even using the native installer (with tolower or a case-insensitive method).
