Nexus Clash

Twice in the last 24 hours, I've lost a big chunk of AP/MP on a fizzled infusion and then 2 minutes later been told the zerg flag has faded. I believe this may be due to picking a lock (accidentally) on the same tile on a different character.

• Is that likely the reason?
• Is there any way to know when I will be able to infuse this tile successfully?
• Could we refrain from mysteriously swallowing 30 AP/MP for nothing? If infusion is prevented for a mystery reason, shouldn't I retain the resources?

Towing this to Squashed Bugs. In the next patch this will no longer take AP/MP and will tell you more explicitly that you've hit an alt guardrail.
