Is anyone else having this problem?

I've 3 star cleared the Dusk Armada boss (Obsidrake) 18 times and have not received a single Repulsive Rod shard. Given that there are only 4 possible rewards for this level and you receive 3 rewards for completing it, it is nearly statistically impossible to not receive Repulsive Rod shards after 18 tries.

No help from IGG. They simply stated that they checked the system and found no discrepancies. I asked if they had actually tested it by clearing the level with an actual account and they responded without actually answering the question (which, in my book, means they didn't).

I created a post on the facebook page asking other players to report whether or not they are able to receive Repulsive Rod shards - hopefully there will be some responses.

I've cleared the level 30 times now (ten 3x Auto-Clears), which is 90 rewards, and still not a single Repulsive Rod shard. Unless they've set the drop rate to something ridiculous like 1/100 this is basically impossible without there being a bug/glitch. I did the math and there's less than a .1% chance (POINT ONE PERCENT) of not receiving a shard after 30 tries if there is an equal chance of receiving each reward. --- Even at a drop rate of 1/40 there's a better than 50% chance of receiving a shard after 30 tries.

I got more rods in the one boss hit after double event than I did across 2 days of 2x 15 boss hits. That's 60 drops. I got 1 drop there. Next day with double event over I got 4 first up.
