Even the events correctly generated:
IERC20.Transfer(
from: 0x0000000000000000000000000000000000000000 (type: address),
to: 0xBf449E4c98361630005ADf5cfb129707d7B0714d (type: address),
value: 500000000000000000000 (type: uint256)
)

Crowdsale.TokensPurchased(
purchaser: 0x46F5862A84Cd5138BE62530AE6a563D4F110DB3e (type: address),
beneficiary: 0x46F5862A84Cd5138BE62530AE6a563D4F110DB3e (type: address),
value: 1000000000000000000 (type: uint256),
amount: 500000000000000000000 (type: uint256)

According to the contract events above, it seems like the token was transferred to the account 0xBf449E4c98361630005ADf5cfb129707d7B0714d rather than the caller account investor1 : 0x46F5862A84Cd5138BE62530AE6a563D4F110DB3e, so maybe you should check your crowdsale contract.

If you can paste all your code, maybe we will find more.

BTW, abcoathup has ever wrote a tutorial about the crowdsale contract, maybe you can have a look at it:
