Do you mean dummy 1 summon dummy 2, dummy 3, etc ...
So the existing dummy becomes overload (too much summon dummy).

If that is the cause, it might be overcome by loop casting. My point is the dummy 1 no longer calls dummy 2, dummy 3, etc ... Instead of dummy 1 he calls himself back. That way there is no more junk data.

Sorry if I'm wrong.

Not sure. But it's more like it's already loop casting. It's more like

Dummy Kitty
Skill: Apply xxx buff

Apply xxx buff
Usage: apply buff and summon dummy kitty

as single player game doesn't crash. And it called like once per second. For single player, it's fine. But for multiplayer, the package of information sent to your counterpart may become huge as it may contain several seconds (it depends on how long it took to load and how Torchlight 2 is coded, but I'm really bad at how data being transferred). If it's the case, the game client may need to load tons of affixes, effects, stat change, creation and destroy of dummy at a very short time. The loading can caused a crash.

Of course, all the above is like assumption and I'm just a self-learner. So my assumption can probably be wrong. As long as there is not a solution, we will never know what happen unless somebody can really hijack the data transaction process and see what's going on, which require much more skills that handling Guts.

I think all my assumption are wrong. The reason why the buff ignores CD is that it's a passive skill. May be switching it into active skills with short duration and shorter CD can help. In fact, if I do kill the dummy on warp and change the duration of the skill into 1.5s, it works on most toggle skills, but not this one as this one use counter to see whether the skill was on. So, can anyone give me some data on whether those classes that may crash the game all have toggle skills? So far, here are two reasons I can think of.
1. We have to kill the dummy, otherwise the game may have the possibility to crash. However, if my memory is correct, nethermancer does kill all the summon (not sure is it includes dummy) on warp and it still causes crash.
2. Duplication of skills. As I notice that sometime there were two same buff icon instead of one when I use Pludgelord. When I saw that, the client will crash for 100% of the times when I change an area.

@Viz @Phanjam @Sch123 : Bug Report came in on Steam :

Bug in Prophetess class
Hello,

For this class. If I respec all skills from the lady the aura will be disabled, but then once I add one point in any passive skill the aura will come even If I put no skill point in it. Could you please check this?


mods are:

Variant classes by Viz
Synergies and essentials patch
Torchlight II essentials
Synergies Mod
evil UI

@Sch123 Thanks so much for suggesting that! Totally slipped my mind to just ask class author Drewrobi. In fact I should ask him to simply hand Phanjam his latest files to make a fix easier. Great call! 

Hi, just found one problem with wilding class, in second tree, first skill- if you want just move mouse curson on this skill it will automatically ctd. Could you fix that ?
