[GAMEPLAY] Confirmed Elise Bugs

I made a thread previously about issues with smartcasting on certain champions. Since then, I've confirmed at least two bugs with Elise's kit that are substantial enough to be gamebreaking to her gameplay, since they cause certain abilities to simply not trigger at all.

1. [Spider Form] E - Rappel

In some instances, when casting Rappel with the cursor outside of her target range, as represented by the circular template, the ability does not cast. The typical behavior for this seems to be to command Elise to move to the location of the cursor before automatically casting Rappel. However, this does not always occur. This seems to happen when in combat with an enemy unit, and it does not cast when the movement is over (Elise reaches the destination), as though the combat presence is interrupting the automatic movement and/or ability casting. Why is this bad? Elise's Rappel is a counter to many champions' ultimates and crowd control abilities, such as Zed, Lux and Jinx. By Rappel having unreliable casting, these ultimates are not always dodged even though the ability should have been cast before impact. This has lead to numerous deaths or lost fights for me already. Solution: Either remove the check it seems to perform to determine if it's in range of the "target" (since sometimes it doesn't go off upon reaching it, and sometimes there is none), so that is casts on self when triggered, or fix the smartcast bugs in the last two patches and hope that fixes the issue of Rappel sometimes failing to go off at the destination or on self.

2. R - Spider Form

In some instances, most notably from Human Form, Elise's ultimate will not cast during combat, even though there is no active crowd control effect preventing her from casting. This most notably happens under area of effect effects, though it's also occurred during basic combat (e.g., when engaging a Nidalee in human form stunned by Cocoon, thus unable to cast against Elise prior to the engagement). How is this broken? The vast majority of Elise's damage comes through her Spider Form kit. Without access to that, and with fresh cooldowns from the Cocoon-Spiderling combo, you are basically left helpless but to lose the trade. Solution: Unknown.

3. W - Volatile Spiderling

Sometimes when casting Volatile Spiderling directly after another ability lands, (in my experience, most notably Cocoon), Elise's Spiderlings will become invisible. This seems to be related to the same bug which allows Nidalee's spears to become invisible as well as Morgana's roots. Gamebreaking why? Do I really need to explain this? Solution: Presumably an animation sequence/missile bug, because it happens commonly with Nid and Morg as well.
