bug: instance warp to overworld via common-event on npc death

[izakt]

Description

When a party of players returns from a Shared Instance -> Overworld, some party members appear to be invisible in the game client. When a player becomes invisible, you can still see damage counts and attack animations from the invisible player. However, you cannot actually target the invisible player.

The player that appears invisible can still send requests to the player that has the visual bug.

It seems to be specific to warping players from an event triggered by NPC On Death event.

Steps to Reproduce

Editor setup:

1. Create two connected maps, "testmap1" and "testmap2".
2. Create a Common Event named "bugtest" with the following Commands:
   @>Warp Player to Overworld instance [Map: testmap1 X: 14 Y: 14]
   
3. Create an NPC named "test npc" with the following Common Events:
   On Death (for killer): [bugtest]
On Death (for party): [bugtest]
   
4. In map "testmap1" create a map event named "warp to instance" with the following Commands:
   @>Warp Player to Shared instance [Map: testmap2 X: 14 Y: 14]
   
5. In map "testmap2", put the NPC "test npc" on the map.
   

Gameplay:

1. Enter the game with two characters, "Char A" and "Char B".
2. Create a party between Char A and Char B.
3. Go to the map named "testmap1" with Char A and Char B.
4. With Char A and Char B, use the map event named "warp to instance" to warp to the shared instance.
5. With Char A and Char B standing within party event trigger range, kill the NPC named "test npc" with Char A.
6. When NPC "test npc" is killed, both characters will warp to the map named "testmap1" via common event named "bugtest" which was triggered by NPC Common Event "On Death".

Actual result: Char A will appear invisible on one of the two player's game clients.
Expected results: Char A and Char B should be able to see each other.

Did you find any workaround?

If you leave the map and then reenter the map, the character that appeared invisible will appear visible again.

If you log out and then log back in, the character that appeared invisible will appear visible again.

I have the same issue in my game-

After many attempts where i was unable to reproduce this, i have to add the following notes which are important in order to reproduce the issue:

• This issue doesn't happens if the instance is the same map where the event triggers the intance warp.
• If the shared instance takes place in another map: then we happen to encounter this reported issue
• This issue only happens when killing enemies, warping out to the overworld through map events doesn't triggers this issue (even if the instance takes place in another map).

@izakt @Arufonsu can you try the latest build? I can not replicate this anymore.

Sadly, i have to inform you that as today (v0.8.0-beta.133), i'm still able to reproduce this issue:

This issue only happens when killing enemies that trigger common events that warps players out to the overworld.
Warping out to the overworld through map events doesn't triggers this issue (even if the instance takes place in another map).

( has anyone happened to test this with parallel events ? )
