reserveTransfer is deleting my bitmap/Sprite?

[peq42_]

I'm using the following code to draw text above some events, and update its position according to the event's position:

$gameMap.event(this._eventId).bitmap = new Bitmap(120, 40);
$gameMap.event(this._eventId).bitmap.outlineWidth = 2;
$gameMap.event(this._eventId).bitmap.fontSize=14;
$gameMap.event(this._eventId).bitmap.drawText($gameMap.event(this._eventId).mynameis,0,0,120,40,"center");$gameMap.event(this._eventId).sprite = new Sprite($gameMap.event(this._eventId).bitmap);$gameMap.event(this._eventId).sprite.z=20;
$gameMap.event(this._eventId).sprite.setFrame(0,0,Graphics.boxWidth, Graphics.boxHeight);
SceneManager._scene.addChild($gameMap.event(this._eventId).sprite);

setInterval(()=>{$gameMap.event(this._eventId).sprite.x=$gameMap.event(this._eventId).screenX() - 60;$gameMap.event(this._eventId).sprite.y=$gameMap.event(this._eventId).screenY() - 80},16)

it works fine, but whenever I perform a $gamePlayer.reserveTransfer (its to the same map) the text gets deleted. Does someone know why?

I noticed that using the reserveTransfer makes the FPS drop. That + the deletion of my bitmap makes me think this function is re-rendering the whole map/events when I run it(even when its a transfer to the same map), but I'm not 100% sure.
